报告摘要：

Liouville system is a system of second order elliptic equations defined on two dimensional spaces. Many models in geometry, physics and biology are interpreted as Liouville systems. In a previous work of myself and Lin (2010 cpam) we established a number of fundamental results for degree counting theorems, which prove existence of solutions by a degree counting formula. In this talk I will report a recent joint work with my student Yi Gu on singular Liouville systems.
