Title: Some results related to the Kazdan-Warner equations

Abstract:

The Kazdan-Warner equation on surface comes from the prescribed Gaussian curvature problem, and also appears in various contexts such as the abelian Chern-Simons-Higgs models. I shall talk about some results related to the Kazdan-Warner equations on surfaces or finite graphs, including the elliptic method and parabolic approach to the Kazdan-Warner equations on surfaces with sigh-changed prescribing function, as well as the topological method to the existence of Kazdan-Warner equations on surfaces or finite graphs.
