题  目：Maslov-type index theory and closed orbits

摘  要：In this talk, I will introduce two kinds of closed orbit problems, i.e., closed geodesics

 on manifolds and closed characteristics on hypersurfaces with the fixed energy. Then I will 

introduce some recent progress in this field, and simply explain how to deal with these problems 

by using the Maslov-type index theory.
