摘要
利用调和函数的偏差性质、系数估计等方法对调和映照类的卷积的凸半径进行了深入研究,得到了一系列精确的结论.此外,通过选取不同的参数值得到凸半径与参数之间的关系.
In this paper,we study the convex radius of convolution of harmonic mapping class by using the deviation property of harmonic function and coefficient estimation,and obtain a series of accurate conclusions.In addition,the relationship between convex radius and parameters is obtained by selecting different parameter values.
