On convex mappings

Complex Variables 2018-08-08 v2

Abstract

We establish a new characterization for a conformal mapping of the unit disk D\mathbb{D} to be convex, and identify the mappings onto a half-plane or a parallel strip as extremals. We also show that, with these exceptions, the level sets of λ\lambda of the Poincar\'e metric λdw\lambda|dw| of a convex domain are strictly convex.
