Large deviations for zeros of $P(\phi)_2$ random polynomials

Probability 2015-05-20 v1

Abstract

We extend results of Zeitouni-Zelditch on large deviations principles for zeros of Gaussian random polynomials ss in one complex variable to certain non-Gaussian ensembles that we call P(ϕ)2P(\phi)_2 random polynomials. The probability measures are of the form eS(f)dfe^{- S(f)} df where the actions S(f)S(f) are finite dimensional analgoues of those of P(ϕ)2P(\phi)_2 quantum field theory. The speed and rate function are the same as in the associated Gaussian case. As a corollary, we prove that the expected distribution of zeros in the P(ϕ)2P(\phi)_2 ensembles tends to the same equilibrium measure as in the Gaussian case.
