Title: Log-concavity of certain natural polynomials
Abstract: The talk should be accessible to a general mathematical audience, even a general scientific audience. Most of it will be about the independent polynomial associated with a matroid and its log-concavity. The log-concavity property of polynomials arising in combinatorics (such as the independence polynomial mentioned above) and representation theory (such as the Schur and Key polynomials) is a topic of contemporary research interest.
