Abstract The aim of this paper is to generalize several differential subordination results, involving arithmetic, geometric and harmonic means of the expressions p(z) and p(z)+zp′(z)p(z). $\begin{array}{} p(z)+\frac{zp'(z)}{p(z)}. \end{array} $ Are also given certain applications of the main results.

微分从属和毕达哥拉斯方法

摘要 本文的目的是推广几个微分从属结果，涉及表达式 p(z) 和 p(z)+zp′(z)p(z) 的算术、几何和调和平均值。$\begin{array}{} p(z)+\frac{zp'(z)}{p(z)}。\end{array} $ 也给出了某些应用的主要结果。
