Abstract

In a recent paper we used a basic decomposition property of polyanalytic functions of order 22 in one complex variable to characterize solutions of the classical \overline{\partial}-problem for given analytic and polyanalytic data. Our approach suggested the study of a special reproducing kernel Hilbert space that we call the H\"ormander-Fock space that will be further investigated in this paper. The main properties of this space are encoded in a specific moment sequence denoted by η=(ηn)n0\eta=(\eta_n)_{n\geq 0} leading to a special entire function E(z)\mathsf{E}(z) that is used to express the kernel function of the H\"ormander-Fock space. We present also an example of a special function belonging to the class ML introduced recently by Alpay et al. and apply a Bochner-Minlos type theorem to this function, thus motivating further connections with the theory of stochastic processes.
