Adjoints of linear fractional composition operators on weighted Hardy spaces

Abstract

It is well known that on the Hardy space H2(D)H^2(\mathbb{D}) or weighted Bergman space Aα2(D)A^2_{\alpha}(\mathbb{D}) over the unit disk, the adjoint of a linear fractional composition operator equals the product of a composition operator and two Toeplitz operators. On S2(D)S^2(\mathbb{D}), the space of analytic functions on the disk whose first derivatives belong to H2(D)H^2(\mathbb{D}), Heller showed that a similar formula holds modulo the ideal of compact operators. In this paper we investigate what the situation is like on other weighted Hardy spaces.
