摘要:

本文的主要目的是为K-准共形保形调和映射类建立几个改进的玻尔不等式、精炼的玻尔型不等式以及精炼的玻尔-罗戈辛斯基不等式的sharp版本。为实现这些目标,我们利用非负量S_ρ(h)以及将主项系数替换为解析函数及其导数的绝对值的概念,以及其他各种设定。此外,我们通过将解析函数h的边界条件替换为半平面条件,获得了单位圆盘内调和映射的精确玻尔-罗戈辛斯基半径。

英文摘要:

The primary objective of this paper is to establish several sharp versions of improved Bohr inequality, refined Bohr-type inequality, and refined Bohr-Rogosinski inequality for the class of $K$-quasiconformal sense-preserving harmonic mappings $f=h+\overline{g}$ in the unit disk $\mathbb{D} := \{z\in\mathbb{C} : |z| < 1\}$. In order to achieve these objectives, we employ the non-negative quantity $S_ρ(h)$ and the concept of replacing the initial coefficients of the majorant series by the absolute values of the analytic function and its derivative, as well as other various settings. Moreover, we obtain the sharp Bohr-Rogosinski radius for harmonic mappings in the unit disk by replacing the bounding condition on the analytic function $h$ with the half-plane condition.
