Seiberg-Witten invariants and surface singularities II. Singularities with good *-action
Andras Nemethi, Liviu I. Nicolaescu
Abstract
This is a continuation of our paper math.AG/0111298. We prove an explicit formula for the geometric genus pg of a quasihomogeneous isolated surface singularity in terms of the Seiberg-Witten invariant of the link and other topological data which can be read from a resolution graph of the singularity. Moreover, we also determine all the Reidemeister-Turaev sign-refined torsion of the link (associated with any spinc structure) in terms of the Seifert invariants.
