A Spanning Tree Model for the Heegaard Floer Homology of a Branched Double-cover
نویسنده
چکیده
Given a diagram of a link K in S, we write down a Heegaard diagram for the brancheddouble cover Σ(K). The generators of the associated Heegaard Floer chain complex correspond to Kauffman states of the link diagram. Using this model we make some computations of the homology d HF (Σ(K)) as a graded group. We also conjecture the existence of a δ-grading on d HF (Σ(K)) analogous to the δ-grading on knot Floer and Khovanov homology.

On the Heegaard Floer Homology of Branched Double-covers
Let L ⊂ S be a link. We study the Heegaard Floer homology of the branched double-cover Σ(L) of S, branched along L. When L is an alternating link, ĤF of its branched double-cover has a particularly simple form, determined entirely by the determinant of the link. For the general case, we derive a spectral sequence whose E term is a suitable variant of Khovanov’s homology for the link L, convergi...
متن کاملBordered Floer Homology and the Spectral Sequence of a Branched Double Cover I
Given a link in the three-sphere, Z. Szabó and the second author constructed a spectral sequence starting at the Khovanov homology of the link and converging to the Heegaard Floer homology of its branched double-cover. The aim of this paper and its sequel is to explicitly calculate this spectral sequence, using bordered Floer homology. There are two primary ingredients in this computation: an e...
متن کاملNotes on the Heegaard-floer Link Surgery Spectral Sequence
In [8], P. Ozsváth and Z. Szabó constructed a spectral sequence computing the HeegaardFloer homology ĤF (YL) where YL is the result of surgery on a framed link, L, in Y . The terms in the E1-page of this spectral sequence are Heegaard-Floer homologies of surgeries on L for other framings derived from the original. They used this result to analyze the branched double cover of a link L ⊂ S3 where...
متن کاملCombinatorial Description of Knot Floer Homology of Cyclic Branched Covers
In this paper, we introduce a simple combinatorial method for computing all versions (∧,+,−,∞) of the knot Floer homology of the preimage of a two-bridge knot Kp,q inside its double-branched cover, −L(p, q). The 4-pointed genus 1 Heegaard diagram we obtain looks like a twisted version of the toroidal grid diagrams recently introduced by Manolescu, Ozsváth, and Sarkar. We conclude with a discuss...
متن کاملKhovanov Homology, Open Books, and Tight Contact Structures
We define the reduced Khovanov homology of an open book (S, φ), and we identify a distinguished “contact element” in this group which may be used to establish the tightness of contact structures compatible with (S, φ). Our construction generalizes the relationship between the reduced Khovanov homology of a link and the Heegaard Floer homology of its branched double cover. As an application, we ...
