Weighted composition operators from weighted-type spaces to Zygmund-type spaces
, 2016 Some criteria for the boundedness and the compactness of weighted composition operators from weighted-type spaces into Zygmund-type spaces are given in this paper. Moreover, we give some estimates for the essential norm of these operators.
