Abstract

Let u ∈ H(D) and φ be an analytic self-map of D. We estimate the essential norms of weighted composition operators uC_φ acting on Zygmund type spaces in terms of u, φ, their derivatives and the n-th power φⁿ of φ. Moreover, we give similar characterizations for boundedness of uC_φ between Zygmund type spaces.
