Bohr–Rogosinski phenomenon for analytic functions and Cesáro operators

Kayumov I.R.; Khammatova D.M.; Ponnusamy S. (2021)

There are a number of articles which deal with Bohr's phenomenon whereas only a few papers appeared in the literature on Rogosinski's radii for analytic functions defined on the unit disk |z|<1. In this article, we introduce ...
On Landau’s Type Estimates for Coefficients of Univalent Functions

Kayumov I.R.; Khammatova D.M.; Wirths K.J. (2020)

© 2020, Springer-Verlag GmbH Germany, part of Springer Nature. In this article we estimate the sum of coefficients for functions with restrictions on the pre-Schwarzian derivative. We obtain an estimate, which is sharp up ...
On the Bohr inequality for the Cesáro operator

Kayumov I.R.; Khammatova D.M.; Ponnusamy S. (2020)

© Académie des sciences, Paris and the authors, 2020. Some rights reserved. We investigate an analog of Bohr's results for the Cesáro operator acting on the space of holomorphic functions defined on the unit disk. The ...
