Abstract:
　

In this talk we consider the problem of minimizing condition numbers over a compact
convex subset of the cone of symmetric positive semi-definite $n\\times n$ matrices.
We show that the condition number is a Clarke regular strongly pseudoconvex function.
We prove that a global solution of the problem can be approximated by an exact or
an inexact solution of a nonsmooth convex program. This asymptotic analysis provides
a valuable tool for designing an implementable algorithm for solving the problem
of minimizing condition numbers.

Biography:
　

Professor Jane Ye received her B. Sc. in pure mathematics from Xiamen University, China in 1982 and her MBA and Ph. D. in applied mathematics from Dalhousie University, Canada in 1986 and 1990 respectively under the supervision of Professor M.A.H. Dempster. She spent two years at the University of Montreal as a postdoctoral researcher under the supervision of Professor F. H. Clarke, then in 1992 took an assistant professor position at the University of Victoria and has been a full professor since 2002. She was a visiting professor at Université de Pau France, Université de Perpignan, and Université de Toulouse III. Professor Ye\'s main research area is optimization and optimal control theory and their application in Economics and Statistics and nonsmooth analysis.
