Some properties of weighted composition operators on algebras of analytic functions. (English) Zbl 1006.47027

Summary: The objects of study in this paper are the weighted composition operators on the disc algebra and the Hardy space \(H^\infty(\mathbb{D})\). For those operators, we prove the equivalence of the compactness, the weak compactness and the complete continuity. Moreover, we give the necessary and sufficient condition for those operators to have closed range or to be Fredholm operators.
