Computations of Floer Homology for Certain Lagrangian Tori in Closed 4-manifolds

چکیده
We compute the Lagrangian Floer cohomology groups of certain tori in closed simply connected symplectic 4-manifolds arising from FintushelStern knot surgery. These manifolds are usually not symplectically aspherical. As a result of the computation we observe examples where HF (L0) = HF (L1) and L0 and L1 are smoothly isotopic but L0, L1 are not symplectically isotopic and are distinguished by HF (L0, L1).

The Künneth Formula in Floer Homology for Manifolds with Restricted Contact Type Boundary
We prove the Künneth formula in Floer (co)homology for manifolds with restricted contact type boundary. We use Viterbo’s definition of Floer homology, involving the symplectic completion by adding a positive cone over the boundary. The Künneth formula implies the vanishing of Floer (co)homology for subcritical Stein manifolds. Other applications include the Weinstein conjecture in certain produ...
متن کاملHolomorphic Disks and Topological Invariants for Closed Three-manifolds
The aim of this article is to introduce certain topological invariants for closed, oriented three-manifolds Y , equipped with a Spinc structure t. Given a Heegaard splitting of Y = U0 ∪Σ U1, these theories are variants of the Lagrangian Floer homology for the g-fold symmetric product of Σ relative to certain totally real subspaces associated to U0 and U1.

متن کاملHeegaard Floer homology of broken fibrations over the circle
This article is the first in a series where we investigate the relations between Perutz’s Lagrangian matching invariants and Ozsváth-Szabó’s Heegaard Floer invariants of three and four manifolds. In this paper, we deal with the purely Heegaard Floer theoretical side of this programme and prove an isomorphism of 3–manifold invariants for certain spinc structures where the groups involved can be ...
متن کاملFloer Homology and Invariants of Homology Cobordism
By using surgery techniques, we compute Floer homology for certain classes of integral homology 3-spheres homology cobordant to zero. We prove that Floer homology is two-periodic for all these manifolds. Based on this fact, we introduce a new integer valued invariant of integral homology 3-spheres. Our computations suggest its homology cobordism invariance.
