题目2：Geodesic orbit metrics on homogeneous spaces constructed by strongly isotropy irreducible spaces
Abstract：In this talk, we will focus on the classification of geodesic orbit metrics on certain homogeneous spaces. Firstly, we will introduce the development on geodesic orbit space and the motivation of our research. Then, we will present our research on a class of homogeneous spaces, which is constructed by two strongly isotropy irreducible spaces. The main tools used here are the principal isotropy subgroups of irreducible representations of simple Lie groups and geodesic graph.
