We compute the Heegaard Floer homology of any rational homology 3-sphere with an open book decomposition of the form (T, Ï†), where T is a genus one surface with one boundary component. In addition,â€¦ (More)

Using a combinatorial approach described in a recent paper of Manolescu, OzsvÃ¡th, and Sarkar we compute the Heegaard-Floer knot homology of all knots with at most 11 crossings (special attention isâ€¦ (More)

We define the reduced Khovanov homology of an open book (S, Ï†), and we identify a distinguished " contact element " in this group which may be used to establish the tightness of contact structuresâ€¦ (More)

We study contact structures compatible with genus one open book decompositions with one boundary component. Any monodromy for such an open book can be written as a product of Dehn twists around dualâ€¦ (More)

We prove that the knot Floer homology of a fibered knot is nontrivial in its nextto-top Alexander grading. Immediate applications include new proofs of Krcatovichâ€™s result that knots with L-spaceâ€¦ (More)

OzsvÃ¡th and SzabÃ³ show in [14] that there is a spectral sequence whose E term is g Kh(L), and which converges to d HF (âˆ’Î£(L)). We prove that the E term of this spectral sequence is an invariant ofâ€¦ (More)

We recently defined invariants of contact 3-manifolds using a version of instanton Floer homology for sutured manifolds. In this paper, we prove that if several contact structures on a 3-manifold areâ€¦ (More)

Supose that Y is a lens space with |H1(Y ; Z)| prime, and Y does not contain a genus one fibered knot. We show that Y contains a knot whose exterior is a once-punctured torus bundle if and only if Yâ€¦ (More)

We prove that Khovanov homology detects the trefoils. Our proof incorporates an array of ideas in Floer homology and contact geometry. It uses open books; the contact invariants we defined in theâ€¦ (More)
