Generalized Composition Operators from Zygmund Type Spaces to Qk Spaces

Let φ be an analytic self-map of D and g∈H(D) . The boundedness and compactness of generalized composition operators

Generalized Weighted Composition Operators from Weighted Bergman Spaces into Zygmund–type Spaces

The boundedness and the compactness of generalized weighted composition operators from weighted Bergman spaces into Zygmund-type spaces are investigated in this paper. Moreover, we give some estimates for the essential norm of these operators.

Weighted composition operators from Bergman-type spaces into Bloch spaces

Let D be the open unit disk in the complex plane C. Denote by H(D) the class of all functions analytic on D. An analytic self-map φ : D → D induces the composition operator Cφ on H(D), defined by Cφ ( f ) = f (φ(z)) for f analytic on D. It is a well-known consequence of Littlewood’s subordination principle that the composition operator Cφ is bounded on the classical Hardy and Bergman spaces (se...

Multilinear Calderón-zygmund Operators on Hardy Spaces

It is shown that multilinear Calderón-Zygmund operators are bounded on products of Hardy spaces.
