关于β级预星像函数的一个子类

On the subclass of a class of analytic functions related prestar like functions of β

引进并研究解析函数族Ｊ（λ，α，β），证明了包含关系，发现Ｊ（λ，α，β）与β级星像函数Ｓ＊（β）之间的一种关系。

The analytic function J(λ,α,β) is introduced and discussed. The contain relation, as well as the relation between J(λ,α,β) and the starlike function S (β) are obtained. Then, the integral formula is given for the function in kind of Q λ(β) function.
