Abstract:Let $\on_{k \in \nz}$ be an orthonormal system on some $\sigma$-finite measure space $(\Om,p)$. We study the notion of cotype with respect to $\Phi$ for an operator $T$ between two Banach spaces $X$ and $Y$, defined by $\fco T := \inf$ $c$ such that \[ \Tfmm \pl \le \pl c \pll \gmm \hspace{.7cm}\mbox{for all}\hspace{.7cm} (x_k)\subset X \pl,\] where $(g_k)_{k\in \nz}$ is a sequence of independent and normalized gaussian variables. It is shown that this $\Phi$-cotype coincides with the usual notion of cotype $2$ iff \linebreak $\fco {I_{\lin}} \sim \sqrt{\frac{n}{\log (n+1)}}$ uniformly in $n$ iff there is a positive $\eta>0$ such that for all $n \in \nz$ one can find an orthonormal $\Psi = (\psi_l)_1^n \subset {\rm span}\{ \phi_k \p|\p k \in \nz\}$ and a sequence of disjoint measurable sets $(A_l)_1^n \subset \Om$ with \[ \int\limits_{A_l} \bet \psi_l\rag^2 d p \pl \ge \pl \eta \quad \mbox{for all}\quad l=1,...,n \pl. \] A similar result holds for the type situation. The study of type and cotype with respect to orthonormal systems of a given length provides the appropriate approach to this result. We intend to give a quite complete picture for orthonormal systems in measure space with few atoms. File length:86K

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send arondineenqrflx.tex end to: banach-files at math.okstate.edu. Abstract: Let $E$ be a Banach space and, for any positive integer $n$, let ${\cal P}(^nE)$ denote the Banach space of continuous $n$-homogeneous polynomials on $E$. Davie and Gamelin showed that the natural extension mapping from ${\cal P}(^nE)$ to ${\cal P}(^nE^{\ast\ast})$ is an isometry into the latter space. Here, we investigate when there is a natural isomorphism between ${\cal P}(^nE)^{\ast\ast}$ and ${\cal P}(^nE^{\ast\ast})$. Among other things, we show that if $E$ satisfies: \break (a) no spreading model built on a normalised weakly null sequence has a lower $q$-estimate for any $q < \infty,$ (b) $E^{\ast}$ has RNP, and (c) $E^{\ast}$ has the approximation property, then ${\cal P}(^nE)$ has RNP for every $n$. Moreover, if $E$ satisfies (a) and is such that $E^{\ast\ast}$ has both the RNP and the approximation property, then ${\cal P}(^nE)^{\ast\ast}$ and ${\cal P}(^nE^{\ast\ast})$ are isomorphic for every $n$. We also exhibit a quasi-reflexive Banach space $E$ for which ${\cal P}(^nE)^{\ast\ast}$ and ${\cal P}(^nE^{\ast\ast})$ are isomorphic for every $n$. Related work has been done recently by (i) M. Gonzalez, (ii) M. Valdivia, and (iii) J. Jaramillo, A. Prieto, and I. Zalduendo. File length:33K

Abstract:It is proved that every function of finite Baire index on a separable metric space $K$ is a $D$-function, i.e., a difference of bounded semi-continuous functions on $K$. In fact it is a strong $D$-function, meaning it can be approximated arbitrarily closely in $D$-norm, by simple $D$-functions. It is shown that if the $n^{th}$ derived set of $K$ is non-empty for all finite $n$, there exist $D$-functions on $K$ which are not strong $D$-functions. Further structural results for the classes of finite index functions and strong $D$-functions are also given. File length:46K

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send asmarmontsmithcnmxfn.ltx end to: banach-files at math.okstate.edu. Abstract:We use the methods of Burkholder, Gundy, and Silverstein to study maximal functions and square functions arising in the construction of the conjugate function on the finite dimensional torus. Using Brownian motion, we obtain dimension-free weak type (1,1) estimates that enable us to prove an analog of the classical Privalov's Theorem for conjugate functions on the disk, in the general setting of a locally compact abelian group with an ordered dual group. In order to do this, we study the structure of measurable orders on locally compact abelian groups, extending the work of H\"older and Hahn. The final result complements previous work of Bochner, Helson and Lowdenslager. File length:128K

We combine these results with combinatorial arguments to address the question of primarity for these spaces and their duals. Our main results are: \medbreak \item{(1)} If $1<p<\infty$, then $B(\ell_p)\approx B(L_p)$ ($B(X)$ consists of the bounded linear operators on $X$). \medbreak \item{(2)} If ${1\over p_i}+{1\over p_j}\leq1$ for every $i\neq j$, or if all of the $p_i$'s are equal, then $\ell_{p_1}\hat{\otimes}\cdots \hat{\otimes}\ell_{p_N}$ is primary. \medbreak \item{(3)} $\ell_p$ embeds into $\ell_{p_1}\hat{\otimes}\cdots \hat{\otimes}\ell_{p_N}$ if and only if there exists $A\subset \{1,2,\cdots,n\}$ such that ${1\over p}=\min\{\sum_{i\in A}{1\over p_i},1\}$. \medbreak \item{(4)} If $1\leq p<\infty$ and $m\geq1$, then the space of homogeneous analytic polynomials ${\cal P}_m(\ell_p)$ and the symmetric tensor product of $m$ copies of $\ell_p$ are primary.

For example, suppose $X_0$ and $X_1$ are K\"othe function spaces on the unit circle $\bold T,$ and let $H_{X_0}$ and $H_{X_1}$ be the corresponding Hardy spaces. Under mild conditions on $X_0,X_1$ we give a necessary and sufficient condition for the complex interpolation space $[H_{X_0},H_{X_1}]_{\theta}$ to coincide with $H_{X_{\theta}}$ where $X_{\theta}=[X_0,X_1]_{\theta}.$ We develop a very general framework for such results and our methods apply to many more general sitauations including the vector-valued case.

Abstract:Necessary and sufficient oscillation conditions are given for a weakly convergent sequence (resp. relatively weakly compact set) in the Bochner-Lebesgue space $\l1$ to be norm convergent (resp. relatively norm compact), thus extending the known results for $\rl1$. Similarly, necessary and sufficient oscillation conditions are given to pass from weak to limited (and also to Pettis-norm) convergence in $\l1$. It is shown that tightness is a necessary and sufficient condition to pass from limited to strong convergence. Other implications between several modes of convergence in $\l1$ are also studied.

Up to a point, the theory of spaces which have this property is independent of the scalar field: the property is self-dual and any space with the property is a finite dimensional space of maximal distance to the Hilbert space of the same dimension. In the case of real scalars only the real line and real $\ell_\infty^2$ have the $2$-summing property. In the complex case there are more examples; e.g., all subspaces of complex $\ell_\infty^3$ and their duals. File length:77K

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send jungeorlczprp.ltx end to: banach-files at math.okstate.edu. Abstract:As is well known absolute convergence and unconditional convergence for series are equivalent only in finite dimensional Banach spaces. Replacing the classical notion of absolutely summing operators by the notion of 1 summing operators \[ \summ_k || Tx_k || \leq c || \summ_k e_k \otimes x_k ||_{\ell_1\otimes_{min}E}\] in the category of operator spaces, it turns out that there are quite different interesting examples of 1 summing operator spaces. Moreover, the eigenvalues of a composition $TS$ decreases of order $n^{\frac{1}{q}}$ for all operators $S$ factorizing completely through a commutative $C^*$-algebra if and only if the 1 summing norm of the operator $T$ restricted to a $n$-dimensional subspace is not larger than $c n^{1-\frac{1}{q}}$, provided $q>2$. This notion of 1 summing operators is closely connected to the notion of minimal and maximal operator spaces. File length:84K

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Subject: Missouri Conference Update
1) To date we have received registrations from over 200 participants from 23 different countries. We can accomodate up to 300 participants. We have received about 60 requests for contributed talks. 2) All those who applied for the dormitory package have been approved. We can support some limited number of additional participants for this package if registration is received before April 1. 3) It would be helpful for us if all those who are able to do so easily can pay their registration fee before arriving. 4) Because of the size of the meeting, we cannot guarantee to accept contributed talks after April 1, 1994.

You may be able to take advantage of various discounted air fares if you make reservations soon, so we would encourage you to take action promptly. The material concerning travel and motel accommodations should be self-explanatory. We also ask that you send back your registration form at your earliest convenience, so that we can start filling in the schedule of talks. It should also be noted that there is an upper limit to the number of participants we can accommodate so we may be forced to decline late registrations. There will be another mailing nearer the conference in which we give a more detailed schedule. If you want to give a 20 or 30 minute talk, your abstract should accompany your registration form. We ask that, if possible, you have your abstract prepared in TeX and that you send us both a hard copy and an electronic copy. Please try to keep your abstract short and to the point, and, in particular, not more than one page (a third to a half a page is much preferred). For joint work, please indicate the speaker with an asterisk (*). We will prepare a list of abstracts in alphabetical order by speaker. These will be distributed at registration. Also, there will be a registration fee of $40. It would assist the organizers if this is paid in advance; of course it is refundable in the event of non-attendance. The fee is waived for the main speakers and graduate students. Please make your check payable to: The University of Missouri, Dept of Mathematics. We also accept payment by Visa or Master Card. Other information, about restaurants, use of e-mail, etc., will also be provided at registration.

Any correspondence by regular mail should be sent to: Analysis Conference Dept Of Mathematics University of Missouri-Columbia Columbia, MO 65211 USA Travelling to and from Columbia, Missouri We describe here the principal means of access to and from Columbia. Details about getting around Columbia will be provided later. CAR The main highways through Columbia are Interstate 70 (I-70) (east-west) and US Highway 63 (north-south). I-70 runs east-west and connects to Kansas City to the west and St. Louis to the east. In particular, St. Louis airport (Lambert field) is situated about 18 miles west of St. Louis directly on I-70. It is about 110 miles from the airport to Columbia. From Kansas City International Airport take I-435 to I-70: it is about 150 miles. Columbia airport is 15 miles south of Columbia on U.S. 63. AIR If flying, you can choose between flying to Columbia, St. Louis and Kansas City. Columbia airport is served by TWE from St. Louis and by Lone Star Airlines from Dallas/Fort Worth. It is about 15-20 miles south of Columbia. We hope to run vans to pick people up there at peak times. There is also Midwest Airport Shuttle (314-874-4048) which charges $11 one-way with $1 extra per additional passenger to the same destination. Taxis are also available (Checker Cab Co. 449-4191). Some motels may also offer shuttle service. >From St. Louis airport you may rent a car; see driving instructions above. Otherwise, there are two choices of public transportation. Tiger Air Express Limousine service to Columbia (314-443-3544 or 800-333-3026) offers door-to-door service at $40 one-way, with departures at approximately one to two-hour intervals. Call to make a reservation. (We can make arrangements for overseas participants) The final departure from St. Louis is at 9:30 p.m. daily. The Greyhound bus operates on the following schedule. Call Greyhound to make sure that this schedule is still valid. Lambert Field to Columbia leave Lambert Field arrive in Columbia 2:40AM 4:40AM 7:50AM 10:05AM 1:50PM 4:20PM 6:40PM 8:45PM Columbia to Lambert Field leave Columbia arrive at Lambert Field 2:40AM 4:45AM 10:05AM 12:20PM 4:20PM 6:35PM Kansas City Airport is somewhat further from Columbia, (about a 3 hour drive). It is also served by Tiger Air Express on a rather less frequent schedule. Contact Tiger Air Express for details. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Motel Information Participants from the US and Canada are asked to make their own reservations directly with the hotel or dormitory. Be sure to ask for the conference rate (you may need to mention that this is a special rate agreed upon with the Math. Dept. for the Analysis Conference). Please make your reservation before the release date (listed below). Participants from outside North America may contact the conference organizers and specify the accommodation required The Johnston/Wolpers(Dorm) and Campus Inn are within walking distance to campus.

We are in the process of seeking additional funds and the final budget situation is not yet clear; we have applied for funds to cover at least some local expenses of all participants, but we will not know if we can do this for some time. Since we are expecting a large attendance, we would like those of you who have other sources of support to use these. We particularly hope to fund graduate students and recent Ph.D's who have no other sources of funding. We have worked out a deal with the Dormitory which will enable us to offer meals in the package if we have a sufficient number signed up by Feb. 15. We are therefore, prepared to guarantee covering the expenses for meals (breakfast, lunch and dinner) and accommodation (at a rate equivalent to double occupancy) at the Dormitory for the first 100 participants who register, pay their registration fee and sign up for such a package before February 15, 1994. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Participants List Name Affiliation Abramovich, Yuri (IUPUI) Alspach, Dale Oklahoma, State Arazy, J.

Abstract:In this paper structure of infinite dimensional Banach spaces is studied by using an asymptotic approach based on stabilization at infinity of finite dimensional subspaces which appear everywhere far away. This leads to notions of asymptotic structures and asymptotic versions of a given Banach space. As an example of application of this approach, a class of asymptotic $l_p$-spaces is introduced and investigated in detail. Some properties of this class, as duality and complementation, are analogous to properties of classical $l_p$ spaces, although the latter is more ``regular'' than its classical counterpart; in contrast, the property exhibited in the uniqueness theorem is very different than for spaces $l_p$.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send casazzajarchowslfcmpct.tex end to: banach-files at math.okstate.edu. Abstract:The question which led to the title of this note is the following: {\it If $X$ is a Banach space and $K$ is a compact subset of $X$, is it possible to find a compact, or even approximable, operator $v:X\to X$ such that $K\subset\ol{v(B_X)}$?} This question was first posed by P.G.Dixon [6] in connection with investigating the problem of the existence of approximate identities in certain operator algebras. We shall provide a couple of observations related to the above question and give in particular a negative answer in case of approximable operators. We shall also provide the first examples of Banach spaces having the approximation property but failing the bounded compact approximation property though all of their duals do even have the metric compact approximation property.

<<<<<<<<<DO NOT REPLY TO THIS MESSAGE.>>>>>>>>>>>>>>>>>>>>> This is the abstract of the paper "Real and complex operator ideals" by J. Wenzel. The paper is typed in AMSLATeX. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send wenzelopidls.ltx end to: banach-files at math.okstate.edu. Abstract:The powerful concept of an operator ideal on the class of all Banach spaces makes sense in the real and in the complex case. In both settings we may, for example, consider compact, nuclear, or $2$--summing operators, where the definitions are adapted to each other in a natural way. This paper deals with the question whether or not that fact is based on a general philosophy. Does there exists a one--to--one correspondence between ``real properties'' and ``complex properties'' defining an operator ideal? In other words, does there exist for every real operator ideal a uniquely determined corresponding complex ideal and vice versa? Unfortunately, we are not abel to give a final answer. Nevertheless, some preliminary results are obtained. In particular, we construct for every real operator ideal a corresponding complex operator ideal and for every complex operator ideal a corresponding real one. However, we conjecture that there exists a complex operator ideal which can not be obtained from a real one by this construction. The following approach is based on the observation that every complex Banach space can be viewed as a real Banach space with an isometry acting on it like the scalar multiplication by the imaginary unit $i$.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send wenzelidltrg.ltx end to: banach-files at math.okstate.edu. Abstract: In this article, we characterize the $UMD$--property of a Banach space $X$ by ideal norms associated with trigonometric orthonormal systems. The asymptotic behavior of that numerical parameters can be used to decide whether or not $X$ is a $UMD$--space. Moreover, in the negative case, we obtain a measure that shows how far $X$ is from being a $UMD$--space. The main result is, that all described parameters are equivalent also in the quantitative setting. File length:37K

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send ariaspopescufock.atx end to: banach-files at math.okstate.edu. Abstract:The framework of the paper is that of the full Fock space ${\Cal F}^2({\Cal H}_n)$ and the Banach algebra $F^\infty$ which can be viewed as non-commutative analogues of the Hardy spaces $H^2$ and $H^\infty$ respectively. An inner-outer factorization for any element in ${\Cal F}^2({\Cal H}_n)$ as well as characterization of invertible elements in $F^\infty$ are obtained. We also give a complete characterization of invariant subspaces for the left creation operators $S_1,\cdots, S_n$ of ${\Cal F}^2({\Cal H}_n)$. This enables us to show that every weakly (strongly) closed unital subalgebra of $\{\varphi(S_1,\cdots,S_n):\varphi\in F^\infty\}$ is reflexive, extending in this way the classical result of Sarason [S]. Some properties of inner and outer functions and many examples are also considered. File length:52K

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send gonzalezgutierrezpolygroth.ltx end to: banach-files at math.okstate.edu. Abstract:A Banach space $E$ has the Grothendieck property if every (linear bounded) operator from $E$ into $c_0$ is weakly compact. It is proved that, for an integer $k>1$, every $k$-homogeneous polynomial from $E$ into $c_0$ is weakly compact if and only if the space ${\cal P}(^kE)$ of scalar valued polynomials on $E$ is reflexive. This is equivalent to the symmetric $k$-fold projective tensor product of $E$ (i.e., the predual of ${\cal P}(^kE)$) having the Grothendieck property. The Grothendieck property of the projective tensor product $E\widehat{\bigotimes}F$ is also characterized. Moreover, the Grothendieck property of $E$ is described in terms of sequences of polynomials. Finally, it is shown that if every operator from $E$ into $c_0$ is completely continuous, then so is every polynomial between these spaces.

Abstract:Letting $E$, $F$ be Banach spaces, the main two results of this paper are the following: (1) If every (linear bounded) operator $E\rightarrow F$ is unconditionally converging, then every polynomial from $E$ to $F$ is unconditionally converging (definition as in the linear case). (2) If $E$ has the Dunford-Pettis property and every operator $E\rightarrow F$ is weakly compact, then every $k$-linear mapping from $E^k$ into $F$ takes weak Cauchy sequences into norm convergent sequences. In particular, every polynomial from $\ell_\infty$ into a space containing no copy of $\ell_\infty$ is completely continuous. This solves a problem raised by the authors in a previous paper, where they showed that there exist nonweakly compact polynomials from $\ell_\infty$ into any nonreflexive space.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send gonzalezgutierrezucpoly.ltx end to: banach-files at math.okstate.edu. Abstract:We prove that weakly unconditionally Cauchy (w.u.C.) series and unconditionally converging (u.c.) series are preserved under the action of polynomials or holomorphic functions on Banach spaces, with natural restrictions in the latter case. Thus it is natural to introduce the unconditionally converging polynomials, defined as polynomials taking w.u.C. series into u.c.\ series, and analogously, the unconditionally converging holomorphic functions. We show that most of the classes of polynomials which have been considered in the literature consist of unconditionally converging polynomials. Then we study several ``polynomial properties'' of Banach spaces, defined in terms of relations of inclusion between classes of polynomials, and also some ``holomorphic properties''. We find remarkable differences with the corresponding ``linear properties''. For example, we show that a Banach space $E$ has the polynomial property (V) if and only if the spaces of homogeneous scalar polynomials ${\cal P}(^k\!E)$, $k\in{\bf N}$, or the space of scalar holomorphic mappings of bounded type ${\cal H}_b(E),$ are reflexive. In this case the dual space $E^*$, like the dual of Tsirelson's space, is reflexive and contains no copies of $\ell_p$. File length:44K

Then it is known that $\normo{\sum f_k}_p \le C \, \normo{\sum g_k}_p$, $1 \le p \le \infty$\ , where the constant $C$\ is independent of $p$. The aim of this paper is to extend this result to certain classes of Orlicz and rearrangement invariant spaces.

Abstract:For each $S \in L(E)$ (with $E$ a Banach space) the operator $R(S) \in L(E^{**}/E)$ is defined by $R(S)(x^{**}+E) = S^{**}x^{**}+E$ \quad ($x^{**}\in E^{**}$). We study mapping properties of the correspondence $S\to R(S),$ which provides a representation $R$ of the weak Calkin algebra $L(E)/W(E)$ (here $W(E)$ denotes the weakly compact operators on $E$). Our results display strongly varying behaviour of $R.$ For instance, there are no non--zero compact operators in Im$(R)$ in the case of $L^1$ and $C(0,1),$ but $R(L(E)/W(E))$ identifies isometrically with the class of lattice regular operators on $\ell^2$ for $E=\ell^2(J)$ (here $J$ is the James' space). Accordingly, there is an operator $T \in L(\ell^2(J))$ such that $R(T)$ is invertible but $T$ fails to be invertible modulo $W(\ell^2(J)).$ File length:57K

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send talagrandcncenmsr.atx end to: banach-files at math.okstate.edu. Abstract:The concentration of measure prenomenon roughly states that, if a set $A$ in a product $\Omega^N$ of probability spaces has measure at least one half, ``most'' of the points of $\Omega^N$ are ``close'' to $A$. We proceed to a systematic exploration of this phenomenon. The meaning of the word ``most'' is made rigorous by isoperimetric-type inequalities that bound the measure of the exceptional sets. The meaning of the work ``close'' is defined in three main ways, each of them giving rise to related, but different inequalities. The inequalities are all proved through a common scheme of proof. Remarkably, this simple approach not only yields qualitatively optimal results, but, in many cases, captures near optimal numerical constants. A large number of applications are given, in particular in Percolation, Geometric Probability, Probability in Banach Spaces, to demonstrate in concrete situations the extremely wide range of application of the abstract tools.

Abstract: We present three methods to construct majorizing measures in various settings. These methods are based on direct constructions of increasing sequences of partitions through a simple exhaustion procedure rather than on the construction of well separated ultrametric subspaces. The first scheme of construction provides a simple unified proof of the Majorizing Measure Theorem for Gaussian processes and of the following fact. If $A,B$ are balanced convex sets in a vector space, and if $A$ is sufficiently convex, a control of the covering numbers $N(A,\varepsilon B)$ for all $\varepsilon>0$ implies the (a priori stronger) existence of a majorizing measure on $A$ provided with the distance induced by $B$. This establishes, apparently for the first time, a clear link between geometry and majorizing measures, and generalizes the earlier results on majorizing measures on ellipsoids in Hilbert space, that were obtained by specific methods. Much of the rest of the paper is concerned with the structure of bounded Bernoulli (=Radmacher) processes. The main conjecture on their structure is reformulated in several ways, that are shown to be equivalent, and to be equivalent to the existence of certain majorizing measures. Two schemes of construction of majorizing measures related to this problem are presented. One allows to describe Bernoulli processes when the index set, provided with the supremum norm, is sufficiently small. The other allows to prove a weak form of the main conjecture. This result, while not sufficient to characterize boundedness of Bernoulli processes, allows to prove the remarkable fact that for any continuous operator $T$ from $C(K)$ to $E$, the Rademacher cotype-2 constant of $T$ is controlled by the maximum of the Gaussian cotype-2 constant of $T$ and of its $(2,1)$-summing norm. It is also proved, as a consequence of one of the main inequalities on Bernoulli processes, that in a Banach space $E$ of dimension $n$, at most $n\log n \log\log n$ vectors suffices to compute the Rademacher cotype $2$ constant of $E$ within a universal constant.

Stephen Montgomery-Smith announces the withdrawal of his paper "The Fourier Transform on Rearrangement Invariant Spaces." This paper was posted to the Banach Bulletin Board under the filename montsmithhdrfyng.tex. This paper is being withdrawn, because a number of Russian authors dealt with the same subject during the 1960's and 70's. In particular, A.B. Gulisa\v svili obtained much stronger results in "Fourier transforms of monotonic functions and the ditribution function" Soviet Math. Dokl., Vol 12 (1971), No. 1 A.B.

<<<<<<<<<DO NOT REPLY TO THIS MESSAGE OR MAIL TO BANACH-DIST.>>>>>>>>>>> This is the abstract of the paper "Differences of bounded semi-continuous functions, I" by H.P. Rosenthal. The paper is typed in AMSTeX. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send rosenthaldbsc.atx end to: banach-files at math.okstate.edu. Abstract:Structural properties are given for $D(K)$, the Banach algebra of (complex) differences of bounded semi-continuous functons on a metric space $K$. For example, it is proved that if all finite derived sets of $K$ are non-empty, then a complex function $\varphi$ operates on $D(K)$ (i.e., $\varphi\circ f\in D(K)$ for all $f\in D(K)$) if and only if $\varphi$ is locally Lipschitz. Another example: if $W\subset K$ and $g\in D(W)$ is real-valued, then it is proved that $g$ extends to a $\tilde g$ in $D(K)$ with $\|\tilde g\|_{D(K)} = \|g\|_{D(W)}$. Considerable attention is devoted to $SD(K)$, the closure in $D(K)$ of the set of simple functions in $D(K)$. Thus it is proved that every member of $SD(K)$ is a (complex) difference of semi-continuous functions in $SD(K)$, and that $|f|$ belongs to $SD(K)$ if $f$ does. An intrinsic characterization of $SD(K)$ is given, in terms of transfinite oscillation sets. Using the transfinite oscillations, alternate proofs are given of the results of Chaatit, Mascioni and Rosenthal that functions of finite Baire-index belong to $SD(K)$, and that $SD(K)\ne D(K)$ for interesting $K$. It is proved that the ``variable oscillation criterion'' characterizes functions belonging to $B_{1/4}(K)$, thus answering an open problem raised in earlier work of Haydon, Odell and Rosenthal. It is also proved that $f$ belongs to $B_{1/4}(K)$ (if and) only if $f$ is a uniform limit of simple $D$-functions of uniformly bounded $D$-norm iff $\osc_\omega f$ is bounded; the last equivalence has also been obtained by V.~Farmaki, using other methods. Elementary computations of the $D$-norm of some special simple functions are given; for example the $D$-norm of $\chix_A$ for a given set $A$ is computed precisely, in terms of $\partial^j A$, the $j$-th boundary of $A$, $j=1,2,\ldots$. The main structural results on $SD(K)$ and $B_{1/4}(K)$ are obtained using the finite oscillations of a given function. The higher order oscillations are exploited for the study of the transfinite analogues of $B_{1/4}(K)$, in subsequent work. File length:184K

Update: CONFERENCE ON POLYNOMIAL INEQUALITIES (Sept. 29 - Oct. 1, 1994) Kent State University, Kent, Ohio 44242. Dear Colleagues, It is a few months since some of you have heard from us about this meeting, and perhaps it is a good idea to give you the very brief update. We have been fortunate that a number of excellent mathematicians have tentatively agreed to participate. Among them are the following: Miroslaw Baran Frank Beaucoup Bernard Beauzamy Anne Bellido Peter Borwein David Boyd Jerome Degot Robert Gardner Narendra Govil Larry Harris William Harris J.C. Hohl Maciej Klimek Norm Levenberg Miguel Lacruz Jose Llavona Yolanda Melendez R.H. Mohapatra Wieslaw Plesniak Bruce Reznick Yannis Sarantopoulos Jozef Siciak Richard Varga We are hoping to have a small-to-medium sized meeting, of around 50-60 mathematicians. Thus, on the one hand, resources may be limited. On the other hand, there is always room for one or two more excellent people! In addition, we would like to do what we can to encourage young people to attend, and your help in bringing them to our attention (and vice versa) would be appreciated. Our financial situation is still not absolutely clear, although things are not completely bleak. In particular, we have recently been informed that the Institute for Mathematics and its Applications (I.M.A.) has awarded a grant to this meeting. As a result, we believe it to be likely that we will be able to pay for the housing (in a nearby motel) for each of the participants for all 3 nights of the meeting. We still have several grant applications pending. As soon as we know the outcome of these applications, we will be able to inform you about whether we will be able to provide additional support for everyone, or whether we will be able to provide travel support for some participants. Needless to say, if you can help us by using other grant money to pay for your travel and/or accommodation, then this would be greatly appreciated, and would free up resources for others. We'll be in touch again by the end of the Summer with further details about the meeting. With best wishes, Richard M. Aron and Andrew M. Tonge (for the organizers) July 14, 1994

We consider the general problem of characterizing conditions under which one can construct an unconditional basis for $X$ by forming an unconditional basis for each $E_n.$ For example, we show that if $\sup \dim E_n<\infty$ and $X$ has Gordon-Lewis local unconditional structure then $X$ has an unconditional basis of this type. We also give an example of a non-Hilbertian space $X$ with the property that whenever $Y$ is a closed subspace of $X$ with a UFDD $(E_n)$ such that $\sup\dim E_n<\infty$ then $Y$ has an unconditional basis, showing that a recent result of Komorowski and Tomczak-Jaegermann cannot be improved.

Subject: GPA in certain courses
I would appreciate if you send me the GPA in your department in the following courses during last academic year. 1) College Algebra 2) Calculus I 3) Calculus II 4) Calculus III In our department, the GPA varied from 1.9 to 2.4 out of 4.00 in recent years. The administrators think that this is low compared to the GPA in humanities and social sciences. Any comments on this topic will be appreciated. Thanks in advance. Elias Saab P.S. I already sent this note to the Mathematics Chairs bulletin board. I got some answers back. If your department had sent me a message about it, then there is no need to respond.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send leungatmcwklp.ltx end to: banach-files at math.okstate.edu. Abstract:Let $\msp$ be a measure space and let $1 < p < \infty$. The {\em weak $L^p$}\/ space $\wlp$ consists of all measurable functions $f$ such that \[ \|f\| = \sup_{t>0}t^{\frac{1}{p}}f^*(t) < \infty,\] where $f^*$ is the decreasing rearrangement of $|f|$. It is a Banach space under a norm which is equivalent to the expression above. In this paper, we pursue the problem of classifying weak $L^p$ spaces isomorphically when $\msp$ is purely atomic. It is also shown that if $\msp$ is a countably generated $\sigma$-finite measure space, then $\wlp$ (if infinite dimensional) must be isomorphic to either $\ell^\infty$ or $\seq$. The results of this article were presented at the conference in Columbia, Missouri in May, 1994. File length:56K

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send dilworthgirardiwkdfptts.atx end to: banach-files at math.okstate.edu. Abstract:For an arbitrary infinite-dimensional Banach space $\X$, we construct examples of strongly-measurable $\X$-valued Pettis integrable functions whose indefinite Pettis integrals are nowhere weakly differentiable; thus, for these functions the Lebesgue Differentiation Theorem fails rather spectacularly. We also relate the degree of nondifferentiability of the indefinite Pettis integral to the cotype of $\X$, from which it follows that our examples are reasonably sharp.

The paper is typed in AMSLATeX. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send brandriisoxh.ltx end to: banach-files at math.okstate.edu. Abstract:Let $X$ be a (real or complex) rearrangement-in\-va\-riant function space on $\Om$ (where $\Om = [0,1]$ or $\Om \subseteq \bbN$) whose norm is not proportional to the $L_2$-norm. Let $H$ be a separable Hilbert space. We characterize surjective isometries of $X(H).$ We prove that if $T$ is such an isometry then there exist Borel maps $a:\Om\to\bbK$ and $\sigma:\Om\lra\Om$ and a strongly measurable operator map $S$ of $\Om$ into $\calB(H)$ so that for almost all $\om$ $S(\om)$ is a surjective isometry of $H$ and for any $f\in X(H)$ $$Tf(\om)=a(\om)S(\om)(f(\sigma(\om))) \text{ a.e.}$$ As a consequence we obtain a new proof of characterization of surjective isometries in complex rearrangement-invariant function spaces.

<<<<<<<<<DO NOT REPLY TO THIS MESSAGE OR MAIL TO BANACH-DIST.>>>>>>>>>>> This is the abstract of the paper "Complemented copies of $\ell^1$ and Pelczynski's property (V*) in Bochner function spaces" by N.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send nrandricomp.ltx end to: banach-files at math.okstate.edu. Abstract: Let $X$ be a Banach space and $(f_n)_n$ be a bounded sequence in $L^1(X)$. We prove a complemented version of the celebrated Talagrand's dichotomy i.e we show that if $(e_n)_n$ denotes the unit vector basis of $c_0$, there exists a sequence $g_n \in \text{conv}(f_n,f_{n+1},\dots)$ such that for almost every $\omega$, either the sequence $(g_n(\omega) \otimes e_n)$ is weakly Cauchy in $X \widehat{\otimes}_\pi c_0$ or it is equivalent to the unit vector basis of $\ell^1$. We then get a criterion for a bounded sequence to contain a subsequence equivalent to a complemented copy of $\ell^1$ in $L^1(X)$. As an application, we show that for a Banach space $X$, the space $L^1(X)$ has Pe\l czy\'nski's property $(V^*)$ if and only if $X$ does.

The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send dawsoncndxpct.atx end to: banach-files at math.okstate.edu. Abstract:Given an operator $T:U_X(\Sigma)\to Y$ or ${T:U(\Sigma)\to Y$, one may consider the net of conditional expectation operators $(T_\pi)$ directed by refinement of the partitions $\pi$. It has been shown previously that $(T_\pi)$ does not always converge to $T$.

The following is the message that CIAC received: --------------------------------------------------------------------------- | Here is some important information. Beware of a file called Goodtimes. | | | | Happy Chanukah everyone, and be careful out there. There is a virus on | | America Online being sent by E-Mail. If you get anything called "Good | | Times", DON'T read it or download it. It is a virus that will erase your | | hard drive. Forward this to all your friends. It may help them a lot. | --------------------------------------------------------------------------- THIS IS A HOAX. Upon investigation, CIAC has determined that this message originated from both a user of America Online and a student at a university at approximately the same time, and it was meant to be a hoax. CIAC has also seen other variations of this hoax, the main one is that any electronic mail message with the subject line of "xxx-1" will infect your computer. This rumor has been spreading very widely. This spread is due mainly to the fact that many people have seen a message with "Good Times" in the header. They delete the message without reading it, thus believing that they have saved themselves from being attacked. These first-hand reports give a false sense of credibility to the alert message. There has been one confirmation of a person who received a message with "xxx-1" in the header, but an empty message body. Then, (in a panic, because he had heard the alert), he checked his PC for viruses (the first time he checked his machine in months) and found a pre-existing virus on his machine. He incorrectly came to the conclusion that the E-mail message gave him the virus (this particular virus could NOT POSSIBLY have spread via an E-mail message). This person then spread his alert. As of this date, there are no known viruses which can infect merely through reading a mail message. For a virus to spread some program must be executed. Reading a mail message does not execute the mail message. Yes, Trojans have been found as executable attachments to mail messages, the most notorious being the IBM VM Christmas Card Trojan of 1987, also the TERM MODULE Worm (reference CIAC Bulletin B-7) and the GAME2 MODULE Worm (CIAC Bulletin B-12). But this is not the case for this particular "virus" alert. If you encounter this message being distributed on any mailing lists, simply ignore it or send a follow-up message stating that this is a false rumor.

Bounds on the Boyd indices in terms of the Matuszewska--Orlicz indices of the defining functions are given. Also, we give an example to show that the Boyd indices and Zippin indices of an Orlicz--Lorentz space need not be equal, answering a question of Maligranda. Finally, we show how the Boyd indices are related to whether an Orlicz--Lorentz space is $p$-convex or $q$-concave. File length:39K

The paper is typed in LATeX. The paper may be downloaded from the bulletin board by ftp to ftp.math.okstate.edu or transmitting the commands begin send pklinextprop.ltx end to: banach-files at math.okstate.edu. Abstract:For any complex Banach space $X$, let $J$ denote the duality mapping of $X$. For any unit vector $x$ in $X$ and any ($C_0$) contraction semigroup $(T_t)_{t>0}$ on $X$, Baillon and Guerre-Delabriere proved that if $X$ is a smooth reflexive Banach space and if there is $x^* \in J(x)$ such that $|\langle T(t) \, x,J(x)\rangle| \to 1 $ as $t \to \infty$, then there is a unit vector $y\in X$ which is an eigenvector of the generator $A$ of $(T_t)_{t>0}$ associated with a purely imaginary eigenvalue. They asked whether this result is still true if $X$ is replaced by $c_o$. In this article, we show the answer is negative. File length:11K

Abstract:K.\ S.\ Lau had shown that a reflexive Banach space has the Mazur Intersection Property (MIP) if and only if every closed bounded convex set is the closed convex hull of its farthest points. In this work, we show that in general this latter property is equivalent to a property stronger than the MIP. As corollaries, we recapture the result of Lau and characterize the w*-MIP in dual of RNP spaces. File length:16K
