They have been studied by many authors, including Masty\l o, Maligranda, and Kami\'nska. In this paper, we consider the problem of comparing the Orlicz--Lorentz norms, and establish necessary and sufficient conditions for them to be equivalent. As a corollary, we give necessary and sufficient conditions for a Lorentz--Sharpley space to be equivalent to an Orlicz space, extending results of Lorentz and Raynaud. We also give an example of a rearrangement invariant space that is not an Orlicz--Lorentz space. \bigskip A.M.S.\ (1980) subject classification: 46E30. \bye Date: Tue, 5 Feb 1991 14:34:26 CST

Denote by $\mu$\ the Haar measure on $G$\ and by $\lambda$\ the normalized Lebesgue measure on $[0,1]$. Using Pisier's recent characterizations of Sidon sets, we prove that there is a constant $c>0$, that depends only on the Sidon constant of $E\cup(-E)$, such that $$ c^{-1} \lambda\left[\normo{\sum\limits^N_{n=1}a_nr_n}\geq c\alpha\right] \leq \mu\left[\normo{\sum\limits^N_{n=1}a_n\gamma_n}\geq \alpha\right] \leq c \lambda\left[\normo{\sum\limits^N_{n=1}a_nr_n}\geq c^{-1} \alpha\right] $$ for all $\alpha > 0$, where $a_1,\ldots,a_N$\ are arbitrary elements of $B$, and $\gamma_1,\ldots,\gamma_N$\ are arbitrary elements of $E$. In order to be able to make fruitful use of Pisier's results, we prove that the Sidon constant of the ``$n$-fold join'' of $E$\ is uniformly bounded independently of $n$. We apply our results to derive new properties of Banach-valued Sidon series that allow us to state necessary and sufficient conditions for the a.e.\ convergence of these series. Moreover, we obtain a principle of contraction of Banach-valued Sidon series, and lower bound estimates on the distribution functions of the scalar-valued version of these series. \bye Date: Mon, 25 Mar 91 14:52:08 +1000

We show that if $M$ is a von Neumann-subalgebra of $B(H)$ which is complemented in B(H) and isomorphic to $M \otimes M$ then $M$ is injective (or equivalently $M$ is contractively complemented). We do not know how to get rid of the second assumption on $M$. In the second part,we show that any complemented reflexive subspace of a $C^*$- algebra is necessarily linearly isomorphic to a Hilbert space. \vfill\eject

This was originally proved by Peter Jones. The proof uses only the boundedness of the Hilbert transform and the classical factorisation of a function in $H^p$ as a product of two functions in $H^q$ and $H^r$ with ${1/q}+{1/r}=1/p$. This proof extends without any real extra difficulty to the non-commutative setting and to several Banach space valued extensions of $H^p$ spaces. In particular, this proof easily extends to the couple $H^{p_{0}}(\ell_{q_0}),H^{p_{1}}(\ell_{q_1}) $, with $1\leq p_{0}, p_{1}, q_{0}, q_{1} \leq \infty$. In that situation, we prove that the real interpolation spaces and the K-functional are induced ( up to equivalence of norms ) by the same objects for the couple $L_{p_0}(\ell_{q_0}),L_{p_1}(\ell_{q_1}) $. In an other direction, let us denote by $C_p$ the space of all compact operators $x$ on Hilbert space such that $tr(|x|^p) <\infty$. Let $T_p$ be the subspace of all upper triangular matrices relative to the canonical basis. If $p=\infty$, $C_p$ is just the space of all compact operators. Our proof allows us to show for instance that the space $H^p(C_p)$ (resp. $T_p$) is the interpolation space of parameter $(1/p,p)$ between $H^1(C_1)$ (resp. $T_1$) and $H^\infty(C_\infty)$ (resp. $T_\i$). We also prove a similar result for the complex interpolation method. Moreover, extending a recent result of Kaftal-Larson and Weiss, we prove that the distance to the subspace of upper triangular matrices in $C_1$ and $C_\infty$ can be essentially realized simultaneously by the same element.

The attack was encouraged by the official opinions of US and EEC that the integrity of Yugoslavia has the top priority in their approaches to solving the crisis in Yugoslavia. It suited very well the communist regimes in Serbia and Montenegro which see the rest of Yugoslavia as greater Serbia which should become a communist country and which have very strong influence on the Yugoslav army. The fight between the federal army and the Slovene army is thus the fight between the remaining communist forces and the newly established democracy in Slovenia. It is of utmost importance for the crisis in Yugoslavia that the official opinions about integrity of Yugoslavia are finally changed to recognizing that the tensions in Yugoslavia are much too great to keep Yugoslavia in one piece, except perhaps by a brutal force which the west has always condemned and which neglects human rights and the right to selfdetermination of every nation and free choice about with whom and how it wands to establish relations. The west should get strongly involved in a controlled dissintegration of Yugoslavia. The first step towards this would be the official re- cognition of the independent and sovereign state of Slovenia. The public opinion has been changing in this direction but the official opinions seem to follow these changes too slowly. Since the official opinion of the west is one of the principal reasons for the encouragement to use the brutal force in Slovenia I would be most grateful if you could use all your available communi- cation channels to convey this message to your government, your media or any relevant institution. I would be most grateful also if you can support Slovenia by adding your personal support to this message. I would also appreciate if you forward this message to any colleague of yours who knows me or who is familiar with my work in mathematics as my mailing list here is very short. With my best regards With my best regards Josip Globevnik email josip.globevnik at uni-lj.ac.mail.yu PS For the case that you are more interested I am providing some details. As you may have heard, the Republic of Slovenia had a plebiscite last December on which more than 90% of the people voted that they wanted that Slovenia becomes an independent and sovereign state. Since that time the Slovene parlament (a multiparty parlament that was elected on free elections in spring a year ago) had been preparing the legislature on the basis of which Slovenia would become an inde- pendent and sovereign state by June 26, half a year from plebiscite. The slovene government and the slovene presidency have been proposing negotiations about this to other republics and to the federal autori- ties several times since last December but there was almost no response to these proposals. Slovenes, a small nation of two million people have never had any conflict with any other nation. We are hard working (I am a tipical example of a Slovene), peaceful people who would only want to live in their own state as this would guarantee that we ourselves would make decisions in the foreign policy and have control at the outflow of our own money. We have not had border problems with Croatia, the only Yugoslav republic that has border with Slovenia. Our mentality is similar to the mentality of people in the nearby Austria. We are culturally part of western culture. We now have a western type parla- mentary system and would like to become a part of integrated Europe. Slovenia became an independent and sovereign state on June 25. On June 27, early in the morning, the federal army's tanks were rolling in different directions out of army posts in Slovenia, mainly towards Ljubljana airport and towards the border crossings on boredrs with Austria and Italy to cut off Slovenia from their western and northern neighbours. It was clear that the Yugoslav army decided to attack brutally in Slovenia. The Slovene army, armed with antitank and antihelicopter missiles began to fight fiercely as it is defending our home. The Yugoslav army in Slovenia collapsed and their units have been blocked since by the Slovene army. Alrea- dy during the second day of fight the Yugoslav army bombed the town of Dravograd, near austrian border. The agreement between Yugoslav prime minister Markovic and Slovene prime minister Peterle was reached yesterday night that army was to move back into its barracks under the supervision of a special technical committee that was yet to be formed. However, the Yugoslav army started moving before such committee was ever formed and this provoked new clashes with Slovene army. New bombings took place this morning. (Slovenes have no airplanes to fight against such bombings). Now the Yugoslav army reserve has been called in Serbia consisting entirely of Serbs are approaching Slovenia.

Dear subscribers, I asked Tim Gowers and Bernard Maurey to make up a sort of abstract of their results for distribution on the bulletin board since the interest in them is so great. Here is a note from Bernard Maurey that I received today. Dale Alspach ----- Begin Included Message ----- From: MAUREY%FRCIRP81.BITNET at CUNYVM.CUNY.EDU Subject: UBSP To: alspach at hilbert.math.okstate.edu, MAUREY at frcirp81.bitnet Status: R
Tim Gowers and the author of these lines independently solved the Unconditional Basic Sequence Problem in the negative; (Tim's solution was the first to appear); we produced almost identical examples of an infinite dimensional Banach space $X$ that does not contain any infinite unconditional basic sequence; we decided to publish jointly the final version of this example and to work together to find more properties of this space. It was observed by Bill Johnson that our space $X$ is Hereditarily Indecomposable, which means that no closed subspace of $X$ is the topological sum of two infinite dimensional closed subspaces. This property obviously implies that $X$ does not contain any infinite unconditional basic sequence. The space $X$ is reflexive, has a monotone basis, and it is possible to show that the dual $X^*$ is also H.I. We proved that complex H.I. spaces have few operators: every operator on a complex H.I. space can be written as $T= \lambda Id + S$, where $S$ is strictly singular; the spectrum of $T$ is finite or consists of a converging sequence of eigenvalues with finite multiplicity (together with the limit). It follows that a complex H.I. space is not isomorphic to any proper subspace, in particular not isomorphic to its hyperplanes. Since we may build our space on the complex field, this provides a second (negative) solution to the hyperplane problem, that was first solved by Tim Gowers. B. Maurey.

Dear Subscribers, Tim Gowers has made available his version of the solution to the unconditional basic sequence problem. The file is in Plain TeX but uses mssymb.tex. If you have upgraded to AMSTeX 2.0 and changed the fonts, you may not be able to use mssymb. To overcome this input amssymb.def and amssym.tex as indicated in the file.

Dear Subscribers, We believe we have found the problem with gowersubsp.tex. The software has trouble with files of over 50K length. We are looking for a better way to handle these files but as a temporary solution all files of length over 50K will be split. For TeX files I will add \input lines to the first part of the file which use the banach-files names for the remaining parts. For example gowersubsp.tex has been split into gowersubsp1.tex and gowersubsp2.tex. The last line of gowersubsp1.tex is \input gowersubsp2.tex. If you change the names or concatenate the files you will need to fix this. Also you will need to request the pieces in two email messages, else the software will try to assemble the pieces into a single file, find that it is too long, and send only the first. In summary to get Tim Gowers TeX file send two email messages to banach-files at hardy.math.okstate.edu First message send gowersubsp1.tex Second message send gowersubsp2.tex Alert me to any further problems. I will also be splitting the older files of length greater than 50K. Dale Alspach

This is the abstract of the paper " Analytic Disks in Fibers over the Unit Ball of a Banach Space" by B.J. Cole, T.W. Gamelin, and W.B. Johnson. The paper is typed in AMSTeX. The paper may be downloaded from the bulletin board by ftp or transmitting the commands in separate messages send colegamjohn1.atx and send colegamjohn2.atx to: banach-files at hardy.math.okstate.edu. We study biorthogonal sequences with special properties, such as weak or weak-star convergence to 0, and obtain an extension of the Josefson-Nissenzweig theorem. This result is applied to embed analytic disks in the fiber over 0 of the spectrum of H^infinity (B), the algebra of bounded analytic functions on the unit ball B of an arbitrary infinite dimensional Banach space. Various other embedding theorems are obtained. For instance, if the Banach space is superreflexive, then the unit ball of a Hilbert space of uncountable dimension can be embedded analytically in the fiber over 0 via an embedding which is uniformly bicontinuous with respect to the Gleason metric.

Let $E$ be a Sidon subset of $\Gamma$ with Sidon constant $S(E)$. Let $r_n$ denote the $n$-th Rademacher function on $[0 , 1]$. We show that there is a constant $c$, depending only on $S(E)$, such that, for all $\alpha > 0$: \begin{eqnarray*} c^{-1}P\left[\left\| \sum_{n=1}^Na_nr_n\right\| \geq c\alpha \right] & \leq & \mu\left[ \left\| \sum_{n=1}^Na_n\gamma_n\right\|\geq \alpha \right] \\ & & \leq \ c\,P\left[\left\| \sum_{n=1}^Na_nr_n\right\| \geq c^{-1}\alpha \right] \end{eqnarray*} where $a_1$, $\ldots$ , $a_N$ are arbitrary elements of $B$, and $\gamma_1$ , $\ldots$ , $\gamma_N$ are arbitrary elements of $E$. We prove a similar result for Sidon subsets of dual objects of compact groups, and apply our results to obtain new lower bounds for the distribution functions of scalar-valued Sidon series. This paper is a rewrite of a paper previously submitted to the noticeboard. \end{abstract} \end{document}
