Toeplitz-Composition C*-Algebras
arXiv:math/0608445
Abstract
Let and be distinct points on the unit circle and suppose that is a linear-fractional self-map of the unit disk D, not an automorphism, with . We describe the C*-algebra generated by the associated composition operator and the shift operator, acting on the Hardy space on D.
