Analytic functions with hyperbolic range and Bohr's inequality

Metric Geometry 2024-03-19 v1

Abstract

We use properties of the hyperbolic metric and properties of the modular function to show that the Bohr's radius for covering maps onto hyperbolic domains is greater or equal to exponential minus pi. This includes almost all known classes of analytic functions.
