Abstract

Let R be a finite Blaschke product of degree at least two with R(0) = 0. Then there exists a relation between the associated composition operator Cr on the Hardy space and the C*-algebra Οr(Jr) associated with the complex dynamical system (Ron)n on the Julia set Jr. We study the C*-algebra τCr generated by both the composition operator Cr and the Toeplitz operator Tz to show that the quotient algebra by the ideal of the compact operators is isomorphic to the C*-algebra Οr(Jr), which is simple and purely infinite.
