Abstract:
Consider a Gaussian Analytic Function on the disk, that is, a random series
whose coefficients are independent complex Gaussians. In joint work with
Yanqi Qiu and Alexander Shamov, we show that the zero set of a Gaussian
Analytic Function is a uniqueness set for the Bergman space on the disk: in
other words, almost surely, there does not exist a nonzero square-integrable
holomorphic function having these zeros. The key role in our argument
is played by the determinantal structure of the zeros given by the PeresVir´ag Theorem, and we prove, in general, that the family of reproducing kernels along a realization of a determinantal point process generates the
whole ambient Hilbert space, thus settling a conjecture of Lyons and Peres. In
a sequel paper, joint with Yanqi Qiu, we study how to recover a holomorphic
function from its values on our random set. The talk is based on the preprints
