Composition operators from Zygmund spaces into Besov Zygmund-type spaces‎

Abstract

‎In this paper first‎, ‎the boundedness and compactness of a composition operator from Zygmund space to Besov Zygmund-type space are studied‎. ‎Then we study this concepts for this operator by using the hyperbolic-type analytic Besov Zygmund-type class‎. ‎Finally‎, ‎we show the relation between the hyperbolic-type analytic Besov Zygmund-type class and the meromorphic (or spherical) Besov Zygmund-type class‎.
