题目: Boundary singularities in the limit space of non-inradius collapsed Riemannian manifolds with boundary

报告人: 张志朗,  佛山科学技术学院

摘要：In this talk, we study two types of boundary singularities of limit space of non-inradius collapsed Riemannian manifolds with boundary, where we assume a lower sectional curvature bound and two sided bound on the second fundamental form of the boundary. We construct some examples to illustrate their complexity. This talk is based on a joint work with Takao Yamaguchi.
