Abstract

In this paper, firstly we obtain characterization for boundedness of the weighted differentiation composition operator  from QK(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.
