报告摘要  Abstract

In Seiberg-Witten gauge theory, one can associate an integer-valued invariant to an oriented smooth closed 4-manifold with b^{+}_2>1. Morgan-Mrowka-Szabó proved a product formula for Seiberg-Witten invariants along three torus. In this talk, I will briefly review the definition of Seiberg-Witten invariant from the perspective of monopole Floer homology, and then sketch an alternating proof of the product formula by using monopole Floer homology. If time permits I will also discuss some applications. This is a joint work with Piotr Suwara.
