Abstract
In this paper, firstly we obtain characterization for boundedness of the weighted differentiation composition operator from Q_K(p,q) space into weighted Zygmund space. Then we give an estimation for the essential norm of such an operator on the mentioned spaces. As an application, we present a characterization for the compactness of the above operator.
Keywords
