报告摘要: In 2001,Ozsvath and Szabo defined a package of 3 and 4-manifold invariants, called Heegaard Floer homology, which has proved to be a very powerful tool to study low dimensional topology problems. Recently, Hanselman, Rasmussen and Watson reinterpreted Heegaard Floer theory in a combinatorial way, i.e. via immersed curves. It helps us to extract and harness information in Heegaard Floer homology more easily. In this talk, I will introduce Hanselman-Rasmussen-Watson's immersed curve invariant and show how to apply it to study Dehn surgery problems.
