The order of the decay of the hole probability for Gaussian random SU(m+1) polynomials

Abstract

We show that for Gaussian random SU(m+1) polynomials of a large degree N the probability that there are no zeros in the disk of radius r is less than $e^{-c_{1,r}{N}^{m+1}}$, and is also greater than $e^{-c_{2,r}{N}^{m+1}}$. Enroute to this result, we also derive a more general result: probability estimates for the event where the volume of the zero set of a random polynomial of high degree deviates significantly from its mean.
