The principal goal of this paper is to extend the classical problem of find the values of $\alpha\in \C$ for which the mappings, either $F_\alpha(z)=\int_0^z(f(\zeta)/\zeta)^\alpha d\zeta$ or $f_\alpha(z)=\int_0^z(f'(\zeta))^\alpha d\zeta$ are univalent, whenever $f$ belongs to some subclasses of univalent mappings in $\D$, but in the case of harmonic mappings, considering the \textit{shear construction} introduced by Clunie and Sheil-Small in \cite{CSS}.

调和映射的某些积分的一价性的一种新方法

本文的主要目标是扩展寻找 $\alpha\in \C$ 的值的经典问题,其映射,或者 $F_\alpha(z)=\int_0^z(f(\zeta)/ \zeta)^\alpha d\zeta$ 或 $f_\alpha(z)=\int_0^z(f'(\zeta))^\alpha d\zeta$ 是单价的,只要 $f$ 属于$\D$ 中的单价映射,但在调和映射的情况下,考虑 Clunie 和 Sheil-Small 在 \cite{CSS} 中引入的 \textit{shear 构造}。
