摘要
In this paper, we give some new essential norm estimates of weighted composition operators uC phi from analytic Besov spaces into the Bloch space, where u is a function analytic on the unit disk D and phi is an analytic self-map of D. Moreover, new characterizations for the boundedness, compactness and essential norm of weighted composition operators uC phi are obtained by the nth power of the symbol phi and the Volterra operators Iu and Ju.
