摘要: 利用推广了的Salagean算子在右半平面内的凸区域D定义了一个n- 螺型函数类, 应用微分从属方法得到了这个函数类的充分条件、包含关系和积分算子等性质, 所得结果推广了一些作者的相关结果.Abstract: A general class of n-spirallike functions with respect to a convex domain D contained in the right half-plane is introduced by using a generalized Salagean operator. Sufficient condition, inclusion relation and integral operator properties of this function class are provided by applying the method of differential subordination, which extends the corresponding results of previous authors.
