Resumen de Heegaard diagrams and Floer homology
Peter S. Ozsváth, Zoltán I. Szabó
We review the construction of Heegaard�Floer homology for closed three-manifolds and also for knots and links in the three-sphere. We also discuss three applications of this invariant to knot theory: studying the Thurston norm of a link complement, the slice genus of a knot, and the unknotting number of a knot. We emphasize the application to the Thurston norm, and illustrate the theory in the case of the Conway link.
