Abstract

We establish the \emph{hole phenomenon} for the Gaussian analytic function Fβ(z)=n=0ξnΓ(2β(n+1))zn, F_{\beta}(z)=\sum_{n=0}^{\infty}\frac{\xi_{n}}{\sqrt{\Gamma\bigl(\frac{2}{\beta}(n+1)\bigr)}}\,z^{n}, associated with the power-exponential weight ezβe^{-|z|^{\beta}} on C\mathbb{C}, where β>0\beta>0. Under the condition that Fβ(z)F_{\beta}(z) has no zeros in D(0,r)D(0,r), the scaled zero counting measure converges to a limiting measure μ0β\mu_{0}^{\beta} vaguely in distribution. This limit exhibits a \emph{forbidden region} {1<z<e1/β}, \bigl\{1<|z|<e^{1/\beta}\bigr\}, which zeros asymptotically avoid. This generalizes the remarkable discovery of Ghosh and Nishry for the Gaussian entire function (the case β=2\beta=2), who first revealed this striking conditional convergence and the emergence of a hole. Our analysis extends their phenomenon to the entire family of power-exponential weights.
