Time & Venue: 2024.10.30 16:00-17:00  思源楼 615

Abstract: 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.
