报告题目:Basic Convex Analysis on Spheres
报告简介:In this talk, aiming at providing an interesting and valuable topic to graduates or younger researchers, we will introduce the basic theory of spherical convexity, including the concepts of spherically convex sets and spherically convex function, and the recent progresses in such a theory. In particular, the combinatorial and the structural properties of spherically convex sets, such as the Radon type, Helly type and Caratheodory type theorems and the Minkowski structural theorems, will be presented, and some properties and criterions of spherically convex functions will also be mentioned.
