Schröder Equation in Several Variables and Composition Operator
Let \varphi be a holomorphic self-map of the open unit ball \mathbb B of \mathbb C^n such that \varphi(0)=0 and that the differential d \varphi_{0} of \varphi at 0 is non singular. The study of the Schröder equation in several complex variables \sigma \circ \varphi = d\varphi _{0} \circ \sigma …
