Fixed Point Composition and Toeplitz-Composition C*-algebras

Katie S. Quertermous

Let $φ$ be a linear-fractional, non-automorphism self-map of $D$ that fixes $ζ \in T$ and satisfies $φ^{'} (ζ) \neq = 1$ and consider the composition operator $C…

A Semigroup Composition C*-algebra

Katie S. Quertermous

For 0 < s < 1, let phi_s(z)=sz+(1-s). We investigate the unital C*-algebra generated by the semigroup {C_{phi_s} : 0 < s < 1} of composition operators acting on the Hardy space of…
