多重调和映射的星形性与凸性

Starlikeness and convexity of polyharmonic mappings

Jiaolong Chen, Antti Rasila, Xiantao Wang

摘要:

本文首先给出了$HC_{p}^{0}$类中多重调和映射值域的一个估计。然后,我们得到了多重调和映射分别是$α$级星形和$β$级凸的两个卷积刻画。最后,在一定的系数条件下,研究了多重调和映射的星形半径和凸性半径。

英文摘要:

In this paper, we first find an estimate for the range of polyharmonic mappings in the class $HC_{p}^{0}$. Then, we obtain two characterizations in terms of the convolution for polyharmonic mappings to be starlike of order $α$, and convex of order $β$, respectively. Finally, we study the radii of starlikeness and convexity for polyharmonic mappings, under certain coefficient conditions.
