The Essential Norm of a Generalized Composition Operator Between Bloch-Type Spaces and Q_K Type Spaces

摘要

Let φ be an analytic self-map of the unit disk D, H(D) the space of analytic functions on D and g ∈ H(D). We define a linear operator as follows, on H(D). In this paper, estimates for the essential norm of the generalized composition operator between Bloch-type spaces and Q_K type spaces are obtained.
