Boundedness and compactness of Hausdorff operators on Fock spaces (2310.01059v2)
Abstract: We obtain a complete characterization of the bounded Hausdorff operators acting on a Fock space $Fp_\alpha$ and taking its values into a larger one $Fq_\alpha,\ 0 < p \leq q \leq \infty,$ as well as some necessary or sufficient conditions for a Hausdorff operator to transform a Fock space into a smaller one. Some results are written in the context of mixed norm Fock spaces. Also the compactness of Hausdorff operators on a Fock space is characterized. The compactness result for Hausdorff operators on the Fock space $F\infty_\alpha$ is extended to more general Banach spaces of entire functions with weighted sup norms defined in terms of a radial weight and conditions for the Hausdorff operators to become $p$-summing are also included.
