Dehn Surgery and 3-Manifolds - 2019 Summer Mini-Course
This mini-course is an introduction to the basic properties of Dehn surgery on knots in 3-manifolds. Dehn surgery was first introduced by Dehn in 1910 as an alternative way to condtruct the Poincaré homology sphere. Since then Dehn surgery has played a important role in 3-manifold theory. The primary resource for this course will be the "Dehn Surgery and 3-Manifolds" notes from the 2016 Park City Mathematics Institute Graduate Summer School by Cameron Gordon. We will also refer to parts on Dale Rolfsen's Knots and Links and "Lectures on Heegaard Floer Homology" by Ozsváth and Szabó. The material should be accessible to anyone comfortable with algebraic topology and differential topology prelim material. Topics will include the cabling conjecture, the Berge conjecture and L-space surgeries.
