Semigroups versus evolution families in the Loewner theory

Complex Variables 2009-07-27 v1 Dynamical Systems

Abstract

We show that an evolution family of the unit disc is commuting if and only if the associated Herglotz vector field has separated variables. This is the case if and only if the evolution family comes from a semigroup of holomorphic self-maps of the disc.
