【摘要】 在复平面单位圆盘内引入β型螺形函数族S_β的一个子类S_α~β函数族,给出了S_α~β族的一个积分表示式和充分必要条件,得到了S_α~β族的第二、三项系数的关系式.
【Abstract】 In this paper,a subclass of spirallike functions of typeβdenoted by S_α~βis introduced in the unit disc of the complex plane.We give an integral representation and one necessary and sufficient condition of S_α~βclass.We also obtain the relative equation between the second and the third coefficient of S_α~βclass.
