Products of Volterra-Type Operators and Composition Operators on logarithmic Bloch Space
Author:
Abstract: Let D = {z : |z| < 1} be the unit disk in the complex plane C, φ be an analytic self-map of D, and g : D → C is an analytic map. We characterize the boundedness and compactness of the products of Volterra-type operators and composition operators CφUg and UgCφ on the logarithmic Bloch space LB and the little logarithmic space LB0 over the unit disk. Some necessary and sufficient conditions are given for which CφUg or UgCφ is a bounded or a compact operator on LB, or LB0, respectively. The results extend the known results about the composition operator to the logarithmic Bloch space LB.
