报告题目 \sigma_2 Yamabe problem on conic 4-sphere

报告摘要: We give a necessary condition for the existence of conic metrics with positive constant $\sigma_2$ curvature on 4-sphere. This is a nonllinear generalization of conic surface theory of Troyanov. Based on the Mass we constrcuted, when singular divisors converges to critical case , we prove that the conic 4-sphere converges to American football in Gromov-Hausdorff topology.  This is  joint work with Hao Fang.
