We consider the family of Gaussian analytic functions in the unit disk, distinguished by the invariance of their zero set with respect to hyperbolic isometries. Let be the number of zeros of in a disk of radius . We study the asymptotic probability of the rare event where there is an overcrowding of the zeros as , i.e. for every , we are looking for the asymptotics of the probability with large compared to the . Peres and Virág showed that for (and only then) the zero set forms a determinantal point process, making many explicit computations possible. Curiously, contrary to the much better understood planar model, it appears that for the exponential order of decay of the probability of overcrowding when is close to is much less than the probability of a deficit of zeros.
