AI 中文摘要
本文引入并研究了归一化多重调和映射的\(\mathcal{W}_{\mathcal{H}_n^0}(\alpha)\)类,其由二阶偏导数的适当界来刻画。我们建立了这个多重调和类与一类相关全纯函数之间的一一对应,从而将Ghosh和Vasudevarao的结果扩展到多复变情形。此外,我们得到了\(\mathcal{W}_{\mathcal{H}_n^0}(\alpha)\)中函数的精确系数界、增长估计和凸组合定理。最后,我们引入多重调和映射的截面(部分和)并研究其对于\(\mathcal{W}_{\mathcal{H}_n^0}(\alpha)\)中函数的性质。
英文摘要
In this paper, we introduce and study the class $\mathcal{W}_{\mathcal{H}_n^0}(α)$ of normalized pluriharmonic mappings, characterized by a suitable bound on their second-order partial derivatives. We establish a one-to-one correspondence between this pluriharmonic class and an associated class of holomorphic functions, thereby extending a result of Ghosh and Vasudevarao \cite{Ghosh-Allu-2019} to the setting of several complex variables. Furthermore, we obtain sharp coefficient bounds, growth estimates and a convex combination theorem for functions in $\mathcal{W}_{\mathcal{H}_n^0}(α)$. Finally, we introduce sections (partial sums) of pluriharmonic mappings and investigate their properties for functions belonging to $\mathcal{W}_{\mathcal{H}_n^0}(α)$.
