چکیده
|
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.
