报告题目：Maslov-type index theory and periodic orbits

报告摘要：In this talk, I will introduce two kinds of periodic orbit problems, i.e., closed orbits on hypersurfaces with the fixed energy and closed geodesics on manifolds. Then I will introduce some recent progress in this field, and explain how to deal with these problems by using Maslov-type index theory.
