Abstract:In this talk, I will introduce two kinds of periodic orbit problems, i.e., closed geodesics on manifolds and closed orbits 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 Maslov-type index theory.
