Title： Universal Inequalities of Laplacian on Riemannian Manifolds and Extensions

Abstract： In this talk, we would like to review some universal inequalities of Laplacian on Riemannian Manifolds. Furthermore, we consider the eigenvalues of Laplacian on the closed Riemannian manifolds. As an application, we give a very sharp upper bound for the second eigenvalue of Laplacian on the isoparametric hypersurface embeded in the unit sphere. Finally, we also give some universal bounds of Xin Laplacian on the translators in the sense of MCF. This is a work joint with Zhouyuan Zeng.
