报告摘要  Abstract

To a 4-manifold X with the same integral homology as S^{1}XS^{3}, one can associate the Casson-Seiberg-Witten invariant \Lambda_{SW} introduced in by Mrowka-Ruberman-Saveliev. In this talk I will discuss several surgery formula for \Lambda_{SW} analogous to that of the Casson invariant. I will also survey some topological applications of \Lambda_{SW}.
