WebApr 6, 2024 · Abstract: We define a model for symplectic cohomology of symmetric product spaces. We discuss its relation to skein algebras. We also generalize Abouzaid's generation criterion for higher-dimensional Heegaard Floer homology. This is joint work with Roman Krutovskiy.

WebMay 23, 2001 · A long exact sequence for symplectic Floer cohomology Paul Seidel The long exact sequence describes how the Floer cohomology of two Lagrangian submanifolds changes if one of them is modified by applying a Dehn twist. We give a proof in the simplest case (no bubbling).
WebThe aim of this paper is to give an introduction to Heegaard Floer homology [24] for closed oriented 3-manifolds. We will also discuss a related Floer homology invariant for knots in S3, [31], [34]. Let Y be an oriented closed 3-manifold.

WebOct 1, 2014 · The algebra structure on the Floer cohomology is computed using the symplectic techniques of Lefschetz fibrations and the topological quantum field theory counting sections of such fibrations. We also show that our results agree with the tropical analogue proposed by Abouzaid, Gross, and Siebert.
