Research Abstract
Our goal in this article is to characterize the boundedness and the compactness of the product of the superposition operator followed by the differentiation operator DSϕ from the H∞ space to the Zygmund space. Moreover, we give the necessary and sufficient conditions for the DSϕ operator from the H∞ space to the Zygmund space to be bounded and compact.
