报告摘要：The classical four vertex theorem describes a fundamental property of simple closed planar curves. It has been extended to space curves, namely a smooth, simple closed curve in $\mathbb{R}^3$ has at least four points with vanishing torsion if it lies on a convex surface. More recently, Ghomi extended this property to curves lying on locally convex surfaces. In this talk we will discuss an interesting approach using the regularity theory of Monge-Ampere equations. This is based on a joint work with Xu-Jia Wang and Bin Zhou.
