Involutive Heegaard Floer Homology
Using the conjugation symmetry on Heegaard Floer complexes, we define a three-manifold invariant called involutive Heegaard Floer homology, which is meant to correspond to Z4-equivariant Seiberg-Witten Floer homology. Further, we obtain two new invariants of homology cobordism, d and d̄, and two invariants of smooth knot concordance, V 0 and V 0. We also develop a formula for the involutive Heeg...
متن کاملHeegaard diagrams and Floer homology
We review the construction of Heegaard–Floer homology for closed three-manifolds and also for knots and links in the three-sphere. We also discuss three applications of this invariant to knot theory: studying the Thurston norm of a link complement, the slice genus of a knot, and the unknotting number of a knot. We emphasize the application to the Thurston norm, and illustrate the theory in the ...
متن کاملHeegaard Floer Homology and Alternating Knots
In [23] we introduced a knot invariant for a null-homologous knot K in an oriented three-manifold Y , which is closely related to the Heegaard Floer homology of Y (c.f. [21]). In this paper we investigate some properties of these knot homology groups for knots in the three-sphere. We give a combinatorial description for the generators of the chain complex and their gradings. With the help of th...
متن کاملHeegaard Floer Homology of Mapping Tori Ii
We extend the techniques in a previous paper to calculate the Heegaard Floer homology groups HF(M, s) for fibered 3-manifolds M whose monodromy is a power of a Dehn twist about a genus-1 separating circle on a surface of genus g ≥ 2, where s is a non-torsion spinc structure on M .
متن کاملHeegaard–floer Homology for Singular Knots
Using the combinatorial description for knot Heegaard–Floer homology, we give a generalization to singular knots that does fit in the general program of categorification of Vassiliev finite–type invariants theory. Introduction Since the categorification of the Jones polynomial by Mikhail Khovanov in 1999 [Kh00], the study of knots and links via homological invariants has remained constantly on ...
