Title: Line ensembles in symmetrized geometric last passage percolation
Abstract:
In this talk, I will discuss symmetrized geometric last passage percolation. This is a prototypical model in the half-space KPZ universality class that has a natural interpretation as a line ensemble (a collection of random continuous functions). The model depends on parameters
, which control the background noise strength away from and at the boundary of the model, respectively. Depending on whether
(subcritical),
(critical), or
(supercritical), the model exhibits different asymptotic behavior, and I will discuss some recent progress in understanding this from a line ensemble perspective.

Title: Optimal rigidity and maximum of the characteristic polynomial of Wigner matrices
Abstract:
We consider two related questions about the extremal statistics of Wigner matrices (random symmetric matrices with independent entries). First, how much can their eigenvalues fluctuate? It is known that the eigenvalues of such matrices display repulsive interactions, which confine them near deterministic locations. We provide optimal estimates for this “rigidity” phenomenon. Second, what is the behavior of the maximum of the characteristic polynomial? This question is motivated by a conjecture of Fyodorov–Hiary–Keating on the maxima of logarithmically correlated fields, and we will present the first results for Wigner matrices. This talk is based on joint work with Paul Bourgade and Ofer Zeitouni.
