Differences of Products of Volterra Type Operators and Composition Operators Between Fock Spaces

Abstract

We characterize boundedness and compactness of the differences of products of Volterra integral operators \(V_g\) (Volterra companion operators \(J_g\)) and composition operators \(C_{\varphi }\) between different Fock spaces \(\mathcal {F}^p(\mathbb {C})\) and \(\mathcal {F}^q(\mathbb {C})\) for every \(p, q \in (0, \infty ]\).
