时间：2023年4月28日 下午4点-5点

地点：五教5107

摘要：In this talk, we shall first review the history of the study of Kazdan-Warner equations on compact Riemann surfaces, which was proposed by Kazdan and Warner (Annals of Math., 1974). Then we shall show the sufficient condition derived by Ding-Jost-Li-Wang (Asian J. Math.,1997). Finally, we shall present our new results on this topic which contain the case that the prescribed function can change signs.
