Computational Mathematics and Scientific Computing Seminar

Joint Spectral Characteristics of Matrices and Semidefinite Programming

Speaker: Raphaël Jungers / MIT

Location: Warren Weaver Hall 1302

Date: Feb. 26, 2010, 10 a.m.


The joint spectral characteristics of matrices are a research topic of growing impact in hybrid systems, combinatorics, numerical analysis, etc. I will survey new applications and techniques, putting an emphasis on numerical analysis questions. I will present new semidefinite optimization techniques, and some related open questions.
