Partition functions of determinantal point processes on polarized Kähler manifolds
25 septembre 2025 - 11:00Salle de séminaires IRMA
Online seminar Abstract: Determinantal point processes (DPPs) on polarized Kähler manifolds are random point processes that can be seen as higher-dimensional generalizations of 2D Coulomb gases. In this talk, I will discuss Zabrodin–Wiegmann type expansions of partition functions and show how they are connected to several concepts in Kähler geometry. In some sense, the asymptotic expansion of the DPP partition function generates geometric objects that generalize some classical ones in Kähler geometry. I will also touch on the effective action of higher-dimensional quantum Hall systems and on random Kähler metrics. -
