Lorentzian polynomials on cones

Algebra Seminar
Time

Speaker
Jonathan Leake – University of Waterloo –

We show how the theory of Lorentzian polynomials extends to cones other than the positive orthant, and how this may be used to prove Hodge-Riemann relations of degree one for Chow rings. If time permits, we will show explicitly how the theory applies to volume polynomials of matroids and/or polytopes. Joint work with Petter Brändén.
