Bohr phenomenon for locally univalent functions and logarithmic power series

Complex Variables 2021-01-12 v1

Abstract

In this article we prove Bohr inequalities for sense-preserving KK-quasiconformal harmonic mappings defined in D\mathbb{D} and obtain the corresponding results for sense-preserving harmonic mappings by letting KK\to\infty. One of the results includes the sharpened version of a theorem by Kayumov et. al.\textit{et. al.} (Math. Nachr.\textit{Math. Nachr.}, 291 (2018), no. 11--12, 1757--1768). In addition Bohr inequalities have been established for uniformly locally univalent holomorphic functions, and for log(f(z)/z)\log(f(z)/z) where ff is univalent or inverse of a univalent function.
