Seiberg-Witten invariants and surface singularities II. Singularities with good $\C^*$-action

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/63110This is a continuation of our paper math.AG/0111298. We prove an explicit formula for the geometric genus p_g 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 spin^c structure) in terms of the Seifert invariants.12 pagesAlgebraic GeometryGeometric Topology4B05, 14J17, 32S25, 57M27, 57R57Seiberg-Witten invariants and surface singularities II.
