Floer cohomology
WebIn this talk, I will show that exact fillings (with vanishing first Chern class) of a flexibly fillable contact (2n-1)-manifold share the same product structure on cohomology if one of the multipliers is of even degree smaller than n-1. The main argument uses Gysin sequences from symplectic cohomology twisted by sphere bundles. In mathematics, Floer homology is a tool for studying symplectic geometry and low-dimensional topology. Floer homology is a novel invariant that arises as an infinite-dimensional analogue of finite-dimensional Morse homology. Andreas Floer introduced the first version of Floer homology, now called … See more Symplectic Floer Homology (SFH) is a homology theory associated to a symplectic manifold and a nondegenerate symplectomorphism of it. If the symplectomorphism is Hamiltonian, the homology arises … See more The Lagrangian Floer homology of two transversely intersecting Lagrangian submanifolds of a symplectic manifold is the homology of a chain complex generated by the intersection points of the two submanifolds and whose differential counts See more Many of these Floer homologies have not been completely and rigorously constructed, and many conjectural equivalences have not been proved. Technical … See more There are several equivalent Floer homologies associated to closed three-manifolds. Each yields three types of homology groups, which fit into an exact triangle. A knot in a three-manifold induces a filtration on the chain complex of each theory, whose … See more This is an invariant of contact manifolds and symplectic cobordisms between them, originally due to Yakov Eliashberg, Alexander Givental See more One conceivable way to construct a Floer homology theory of some object would be to construct a related spectrum whose ordinary homology is the desired Floer homology. Applying … See more Floer homologies are generally difficult to compute explicitly. For instance, the symplectic Floer homology for all surface symplectomorphisms was completed only in 2007. The Heegaard Floer homology has been a success story in this regard: researchers have … See more

Two knots K 0 and K 1 are called (smoothly) concordant if there is a smoothly embedded annulus A⊂ S3 × [0,1] with A∩ (S3 × {i}) = Ki× {i} for i= 0,1.A knot concordant to the unknot is called slice.In fact, there is a notion of slice genus for a … Web1.1 What is Floer (co)homology 1 1.2 General theory of Lagrangian Floer cohomology 5 1.3 Applications to symplectic geometry 13 1.4 Relation to mirror symmetry 16 1.5 Chapter-wise outline of the main results 25 1.6 Acknowledgments 35 1.7 Conventions 36 Chapter 2.

WebAbstract: Floer Cohomology groups are important tools that are used to study many geometric and dynamical problems in symplectic geometry. However it is difficult to compute these groups in general.

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. The simplest version of Heegaard Floer homology associates to Y a nitely generated Abelian
