Workshop Schedule

Wednesday, February 24, 2021
  • 3:30 - 4:30 pm EST
    Log-Concavity of Littlewood-Richardson Coefficients
    • Avery St. Dizier, Univeristy of Illinois at Urbana-Champaign
    We describe a log-concavity property of the Littlewood--Richardson numbers and explain its connection to the theory of Lorentzian polynomials.
Wednesday, March 3, 2021
  • 4:00 - 5:00 pm EST
    Quantum integrability and Grassmannians
    • Paul Zinn-Justin, The University of Melbourne
    We will investigate in the simplest setting, how an``R-matrix'' (the building block of ``quantum integrable systems'') is attached to the equivariant cohomology of Grassmannians. We will compute the R-matrix in the case of CP^1 and discuss how the result generalizes to arbitrary Grassmannians. As an application, we shall derive the AJSBilley formula (restriction of Schubert classes to fixed points).
