报告摘要:In this talk, I will introduce Pogorelov type interior $C^2$ estimates about Sum Hessian equations. We establish respectively Pogorelov type $C^2$ estimates for k-convex solutions and admissible solutions under some conditions. Furthermore, we apply such estimates to obtain a rigidity theorem for k-convex solutions of Sum Hessian equations in Euclidean space.
