Abstract

Let Ω\Omega be a bounded pseudoconvex domain in Cn\mathbb{C}^n, and let ϕ\phi be a strictly plurisubharmonic function on Ω\Omega. For each kNk\in\mathbb{N}, we consider determinantal point process Λk\Lambda_k with kernel KkϕK_{k\phi}, where KkϕK_{k\phi} is the reproducing kernel of infinite dimensional weighted Bergman space H(kϕ)H(k\phi) with weight ekϕe^{-k\phi}. We show that the scaled cumulant generating function for Λk\Lambda_k converges as kk\rightarrow\infty to a certain limit, which can be explicitly expressed in terms of ϕ\phi and a test function uu. Note that we need to restrict the type of test function uu to those that are ϕ\phi-admissible.
