2025年学术讲座预告（No.28）北京大学大学张瑞珈博士做报告

报告题目：estimates for k-Hessian equations and a rigidity theorem

报告摘要：We derive a concavity inequality for k-Hessian operators under the semiconvexity condition.As an application, we establish interior estimates for semiconvex solutions to the k-Hessian equations with vanishing Dirichlet boundary conditions and obtain a Liouville-type result. This result confirms Chang-Yuan's conjecture under the super quadratic growth condition.
