• Wednesday, September 9, 9:00-10:00, Zoom link (ID: 830 0216 4749, Code: 752097)
  Antoine Song (California Institute of Technology) - On the geometry of large sets - Abstract

  I will talk about what happened behind the resolution of Talagand's convexity conjecture (with Dongming Merrick Hua and Stefan Tudose) and propose new directions, in particular a Riemannian version of the conjecture for manifolds with nonnegative Ricci curvature.

  
  

• Wednesday, September 16, 9:00-10:00, Zoom link (ID: 834 6727 7014, Code: 440423)
  Biao Ma (East China Normal University) - Gårding polynomials and applications in PDEs and Combinatorics - Abstract

  Motivated by the classical hyperbolic polynomials and Caffarelli-Nirenberg-Spruck theory, we introduce Gårding and ideal Gårding polynomials to capture the ellipticity and convexity features that appear in fully nonlinear PDEs. I will discuss some interesting properties and their connections to real stable and Lorentzian polynomials. Applications in fully nonlinear PDEs and combinatorics will be discussed, including a new Liouville type Theorem, Rayleigh inequalities and log-concavity for matroids and graphs. This talk is based on joint works with Hao Fang and Jinyang Wu.
