Complex symmetric composition operators with automorphic symbols

Functional Analysis 2016-08-02 v3

Abstract

In this paper we show that a composition operator CφC_\varphi cannot be complex symmetric on Hardy-Hilbert space H2(D)H^2(D) when φ\varphi is an elliptic automorphism of order 33 and not a rotation. This completes the project of finding all invertible composition operators which are complex symmetric H2(D)H^2(D).
