Abstract:

Suppose φ is an analytic map of the unit disk D into itself, X is a Banach space of analytic functions on D.
Define the composition operator Cφ : Cφ (f)=f ο φ , for all  ∈ X. In this paper, the boundedness of the composition operators from hyperbolic α-Bloch spaces into hyperbolic QK type spaces are discussed, where 0 < α ≤ 1. Moreover, a necessary and sufficient condition for Cφ from weighted Dirichlet space Dp, α to QK(p, q) to be bounded or compact is given in terms of the map φ.

Key words: Composition operator, Analytic function, Weighted Dirichlet space
