Title: Applications of stable polynomials to matix inequalities
Abstract of Talk
Polynomials in one variable with only real roots abound in many diverse areas, particularly so in combinatorics. A multivariate generalization of such polynomials has been very effectively used in a recent approach, developed by Borcea and Branden, and their work has resulted in spectacular solutions to several long standing problems. We describe some of this work pertaining to permanents, mixed determinants and mixed discriminants.
