报告摘要

1. Public lecture:

Title: 我的三十年河西

Abstract: 作为一位数学教授,我将会分享我在美国三十年的经历与感悟。

 2. Research talk:

Title: Orbital geometry - from matrices to Lie   groups

Abstract: The celebrated Toeplitz-Hausdorff   theorem asserts that the classical

numerical range of a square complex matrix   is a convex set. Schur-Horn Theorem

asserts that the set of the diagonals of   Hermitian matrices of a prescribed

eigenvalues is the convex hull of the   orbit of the eigenvalues under the action

 of the symmetric groups. These   results are about unitary orbit of a matrix.

Among interesting generalizations,   we will focus our discussion on those

in the context of Lie structure, more   precisely, compact connected Lie groups

and semisimple Lie algebras. Some   results on convexity and star-shapedness

will be presented.
