The theta divisor and the Casson-Walker invariant
Peter Ozsvath, Zoltan Szabo
We use Heegaard decompositions and the theta divisor on a Riemannian surface to define a three-manifold invariant for rational homology three-spheres. This invariant is defined on…

The Theta Divisor and Three-Manifold Invariants
Peter Ozsvath, Zoltan Szabo
In this paper we study an invariant for oriented three-manifolds with , which is defined using Heegaard splittings and the theta divisor of a Riemann surface. The paper is d…
