Higher Order Derivative Characterization for Fock-Type Spaces

Abstract

In this paper, we give a characterization for the Fock-type space \({\mathcal{F}_{\alpha}^{\infty}(\mathbb{C}^N)}\) in terms of higher order derivatives of f and behaviors of local integral means of those derivatives. The space \({\mathcal{F}_{\alpha}^{\infty}(\mathbb{C}^N)}\) has the closed subspace \({\mathcal{F}_{\alpha, 0}^{\infty}(\mathbb{C}^N)}\). We also characterize this subspace via higher order derivatives. As an application we study the boundedness and compactness of the extended Cesaro operator Tg on \({\mathcal{F}_{\alpha}^{\infty}(\mathbb{C}^N)}\) and \({\mathcal{F}_{\alpha, 0}^{\infty}(\mathbb{C}^N)}\).
