# Heegaard Floer homology and genus one, one‐boundary component open books

@article{Baldwin2008HeegaardFH, title={Heegaard Floer homology and genus one, one‐boundary component open books}, author={John A. Baldwin}, journal={Journal of Topology}, year={2008}, volume={1} }

We compute the Heegaard Floer homology of any rational homology 3‐sphere with an open book decomposition of the form (T, ϕ), where T is a genus one surface with one‐boundary component. In addition, we compute the Heegaard Floer homology of every T2‐bundle over S1 with first Betti number equal to 1, and we compare our results with those of Lebow on the embedded contact homology of such torus bundles. We use these computations to place restrictions on Stein‐fillings of the contact structures…

### A spanning tree model for the Heegaard Floer homology of a branched double‐cover

Given a diagram of a link K in S3, we write down a Heegaard diagram for the branched‐double cover Σ(K). The generators of the associated Heegaard Floer chain complex correspond to Kauffman states of…

By recent results of Baker, Etnyre and Van Horn-Morris, a rational open book decomposition defines a compatible contact structure. We show that the Heegaard Floer contact invariant of such a contact…

We study the left-orderability of the fundamental groups of cyclic branched covers of links which admit co-oriented taut foliations. In particular we do this for cyclic branched covers of fibered…

We use the Ozsvath-Szabo theory of Floer homology to define an invariant of knot complements in three-manifolds. This invariant takes the form of a filtered chain complex, which we call CF_r. It…
