Compactness and norm of the sum of weighted composition operators on A(ⅅ)

Abstract

Let A(D{double-struck}) denote the disk algebra and uCφ be the weighted composition operator on A(D{double-struck}). In this paper, we characterize the compactness of sum of weighted composition operators on A(D{double-struck}). Furthermore, we also find the norm of sum of weighted composition operators on A(D{double-struck}).
