Lorentzian polynomials
June Huh (Princeton University)
Abstract: Lorentzian polynomials link continuous convex analysis and discrete convex analysis via tropical geometry. The tropical connection is used to produce Lorentzian polynomials from discrete convex functions. Specific examples can be constructed from graphs, convex bodies, stable polynomials, irreducible representations of general linear groups, and in particular, projective varieties. I will explain the main ideas from the viewpoint of algebraic geometry. Based on joint work with Petter Branden.
