Bohr-Rogosinski type inequalities for concave univalent functions

Complex Variables 2022-05-02 v1

Abstract

In this paper, we generalize and investigate Bohr-Rogosinski's inequalities and the Bohr-Rogosinski phenomenon for the subfamilies of univalent (i.e., one-to-one) functions defined on unit disk D:={zC:z<1}\mathbb{D}:=\{z\in \mathbb{C}:|z|<1 \} which maps to the concave domain, i.e., the domain whose complement is a convex set. All the results are proved to be sharp.
