∞ n=0 |an| (1/3) = 1 if and only if f is a constant function. However, there are a lot of generalizations and extensions of this theorem (cf. [12–14, 29]). The interest on this topic was revived due to the discovery of extensions to domains in C and to more general abstract setting in various contexts, due mainly to works of Aizenberg, Boas, Khavinson, and others (cf. [2–4, 8, 10, 25]). In [2, 4], multidimensional analogues of Bohr’s inequality in which the unit disk D is replaced by a domain…

A generalized Bohr-Rogosinski phenomenon

In this paper, we generalize the Bohr-Rogosinski sum for the Ma-Minda classes of starlike and convex functions. Also the phenomenon is studied for the classes of starlike functions with respect to

Bohr radius for Banach spaces on simply connected domains

Let H∞(Ω, X) be the space of bounded analytic functions f(z) = ∑∞ n=0 xnz n from a proper simply connected domain Ω containing the unit disk D := {z ∈ C : |z| < 1} into a complex Banach space X with

A generalization of the Bohr inequality for bounded analytic functions on simply connected domains and its applications

Bohr's classical theorem and its generalizations are now active areas of research and have been the source of investigations in numerous function spaces. In this article, we study a generalized

Generalization of Bohr-type inequality in analytic functions

The purpose of the present article is to show several refined and generalized Bohr-type inequality. These results are based on recent investigation and various generalizations. Moreover, the

A generalization of the Bohr-Rogosinski sum

Abstract. In this paper, we investigate the Bohr-Rogosinski sum and the classical Bohr sum for analytic functions defined on the unit disk in a general setting. In addition, we discuss a

Note on Improved Bohr Inequality for harmonic mappings

Let D = {z ∈ C : |z| < 1} denote the open unit disk and H∞ denote the class of all bounded analytic functions f on the unit disk D with the supremum norm ‖f‖∞ := supz∈D |f(z)|. Also, let B = {f ∈ H∞

Note on Weighted Bohr’s Inequality

Abstract In this paper, first we give a new generalization of the Bohr’s inequality for the class of bounded analytic functions $$\mathcal{B^{\prime}}$$ and for the class of sense-preserving $$K$$

Modifications of Bohr's inequality in various settings

Abstract. The concept of Bohr radius for the class of bounded analytic functions was introduced by Harald Bohr in 1914. His initial result received greater interest and was

Cesàro averaging operators

We define a family of Cesàro operators $ {\cal C} ^{\vec \gamma} $ on the polydisc Un, and consider the question of its boundedness on some spaces of analytic functions.

On the Bohr inequality for the Cesáro operator

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 asymptotical behaviour of the corresponding Bohr sum is

New Inequalities for the Coefficients of Unimodular Bounded Functions

The classical inequality of Bohr asserts that if a power series converges in the unit disk and its sum has modulus less than or equal to 1, then the sum of absolute values of its terms is less than
