On the Conformal Lens Map

Complex Variables 2023-12-22 v1

Abstract

It is well-known that lens maps are convex mappings defined in the unit disc to itself. In this brief note, we show that these mappings are convex of order α>0\alpha>0, and starlike of order β>0\beta>0, and establish the precise orders in terms of opening angle of the lens map.
