报告摘要  Abstract

An isometric group action on a Riemannian manifold (M, g) by a compact Lie group G is called polar if there is a connected, closed, embedded submanifoldof M which meets all the orbits orthogonally. There is a rich theory of polar actions. We will give an introduction to this rich theory
