Rational homology spheres and four-ball genus

Geometric Topology 2007-05-23 v1

Abstract

Using the Heegaard Floer homology of Ozsvath and Szabo we investigate obstructions to definite intersection pairings bounded by rational homology spheres. As an application we obtain new lower bounds for the four-ball genus of Montesinos links.
