Abstract In Ozsvath and Szabo (Holomorphic triangles and invariants for smooth four-manifolds, math. SG/0110169, 2001), we introduced absolute gradings on the three-manifold invariants developed in Ozsvath and Szabo (Holomorphic disks and topological invariants for closed three-manifolds, math.SG/0101206, Ann. of Math. (2001), to appear). Coupled with the surgery long exact sequences, we obtain a number of three- and four-dimensional applications of this absolute grading including… Expand

Knotted surfaces in 4-manifolds
Abstract. Fintushel and Stern have proved that if is a symplectic surface in a symplectic 4-manifold such that has simply-connected complement and nonnegative self-intersection, then there areExpand
An Ozsvath-Szabo Floer homology invariant of knots in a contact manifold ⋆
Abstract Using the knot Floer homology filtration, we define invariants associated to a knot in a three-manifold possessing non-vanishing Floer co(homology) classes. In the case of the Ozsvath–SzaboExpand
Floer homology and knot complements
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. ItExpand
On knot Floer homology and lens space surgeries
Abstract In an earlier paper, we used the absolute grading on Heegaard Floer homology HF + to give restrictions on knots in S 3 which admit lens space surgeries. The aim of the present article is toExpand
Definite manifolds bounded by rational homology three spheres
This paper is based on a talk given at the McMaster University Geometry and Topology conference, May 2004. The basic question we address is whether a given definite form may be the intersectionExpand
Knot Floer homology and relative adjunction inequalities.
We establish inequalities that constrain the genera of smooth cobordisms between knots in 4-dimensional cobordisms. These "relative adjunction inequalities" improve the adjunction inequalities forExpand
On the Heegaard Floer homology of Dehn surgery and unknotting number
In this thesis we generalise three theorems from the literature on Heegaard Floer homology and Dehn surgery: one by Ozsvath and Szabo on deficiency symmetries in half-integral L-space surgeries, andExpand
Closed geodesics and Fr{\o}yshov invariants of hyperbolic three-manifolds
Frøyshov invariants are numerical invariants of rational homology three-spheres derived from gradings in monopole Floer homology. In the past few years, they have been employed to solve a wide rangeExpand
Holomorphic disks and knot invariants
Abstract We define a Floer-homology invariant for knots in an oriented three-manifold, closely related to the Heegaard Floer homologies for three-manifolds defined in an earlier paper. We set upExpand
On concordances in 3-manifolds
We describe an action of the concordance group of knots in S3 on concordances of knots in arbitrary 3-manifolds. As an application we define the notion of almost-concordance between knots. After someExpand


Holomorphic disks and three-manifold invariants: Properties and applications
In [27], we introduced Floer homology theories HF - (Y,s), HF∞(Y,s), HF + (Y, t), HF(Y,s),and HF red (Y, s) associated to closed, oriented three-manifolds Y equipped with a Spiny structures s ∈ SpinExpand
Dehn surgery on knots
In [D], Dehn considered the following method for constructing 3-manifolds: remove a solid torus neighborhood N(K) of some knot X in the 3-sphere S and sew it back differently. In particular, heExpand
Bounds on genus and geometric intersections from cylindrical end moduli spaces
In this paper we present a way of computing a lower bound for genus of any smooth representative of a homology class of positive self-intersection in a smooth four-manifold $X$ with second positiveExpand
The Seiberg-Witten equations and four-manifolds with boundary
An early result by Donaldson says that if Z is closed and JZ is negative definite then JZ is isomorphic to some diagonal form 〈−1〉 ⊕ · · · ⊕ 〈−1〉. More generally one may ask which negative definiteExpand
