Title: Log-Concavity of Littlewood-Richardson Coefficients

Abstract:  Schur polynomials and Littlewood-Richardson numbers are classical objects arising in symmetric function theory, representation theory, and the cohomology of the Grassmannian. I will give a quick introduction to them, and then describe a new log-concavity property of the Littlewood-Richardson numbers. I will then explain the mechanism behind the log-concavity, Brändén and Huh's theory of Lorentzian polynomials.
