一类负系数函数族的Hadaman乘积性质

The nature of hadaman product of one class of univalent functions with negative coefficients

本文构造一类单位圆盘内的非负单叶解析函数族,利用已知结论,得到这类函数族的Hadaman乘积性质。

The author constructs a new class of univalent functions with negative coefficients in the unit Dis. From the conclu- sion, the nature of hadaman product of the functions is obtained
