定义了一个新的解析函数类C(λ,β,A,B),它是杨定恭一文中的函数类推广,并导出了C(λ,β,A,B)函数类的偏差定理,实部的估计和系数估计等性质.
In this paper, we define a new class of analytic functions C(λ,β,A,B) , which is the generalization of the class of analytic functions of the paper of Xang Ding-gong. The object of the present paper is to derive distortion theorems, real-part estimates, coefficient estimates etc. for the class C ( λ,β,A,B) .
