Abstract:
he compactness of differences of weighted composition operators between weighted Bergman spaces of analytic functions on the open unit disk D in terms of inducing symbols ,ψ:D→D and u,v:D→C are characterized. Finally, a sufficient condition for compactness and essential norm of the difference operator between weighted Bergman spaces is given.
Key words: weighted composition operator; weighted bergman space; compactness; essential norm
