Complex symmetric composition operators with automorphic symbols (1607.04801v3)
Published 16 Jul 2016 in math.FA
Abstract: In this paper we show that a composition operator $C_\varphi$ cannot be complex symmetric on Hardy-Hilbert space $H2(D)$ when $\varphi$ is an elliptic automorphism of order $3$ and not a rotation. This completes the project of finding all invertible composition operators which are complex symmetric $H2(D)$.
