Sum of hermitian squares decompositions of non-commutative polynomials
Wednesday 17 September 2014 at 15.00, JCMB 6206

Abstract

I will present problems related to the positivity of real polynomials in non-commutative variables and describe solution approaches using semidefinite programming. I will also discuss (constrained) eigenvalue and trace optimization of non-commutative polynomials and give a demonstration of the Matlab software package NCsostools on a few examples.
