Hilbert-Schmidt composition-differentiation operators on the unit ball (2308.15045v1)
Published 29 Aug 2023 in math.FA
Abstract: We use the notion of radial derivative to introduce composition-differentiation operators on the Hardy and Bergman spaces of the unit ball and the polydisk. We seek for necessary and sufficient conditions on the inducing functions to ensure that the composition-differentiation operator is Hilbert-Schmidt.
