Pluripotential Theory and Convex Bodies: Large Deviation Principle (1807.11369v1)

Abstract: We continue the study in a previous work in the setting of weighted pluripotential theory arising from polynomials associated to a convex body $P$ in $({\bf R}^+)^d$. Our goal is to establish a large deviation principle in this setting specifying the rate function in terms of $P-$pluripotential-theoretic notions. As an important preliminary step, we first give an existence proof for the solution of a Monge-Amp`ere equation in an appropriate finite energy class. This is achieved using a variational approach.
