Abstract: When φ is an analytic map of the unit disk D into itself, and X is a Banach space of analytic functions on D, define the composition operator Cφ by Cφ(f) = f ο φ, for f ∈ X. In this paper, we study the boundedness and compactness of composition operators from the space B0 to QK and QK,0.

Key words:  bounded operator, compact operator, composition operator, analytic function
