关于β级预星象函数的子族的一个不等式

On a inequality of the subclass of a class of analytic functions related prestarlike functions of β

引进并研究解析函数族 J(λ,α,β) ,发现 J(λ,α,β)与 β级星象函数族之间的一种新关系 ,并应用此关系及一阶微分从属证明关于实部的一个不等式 ,由此得到了β级

The analytic function J(λ,α,β) is introduced and discussed,the new relation between J(λ,α,β) and the starlike function s *(β) are obtained.Making use of this relation and differential subordination,a inequality on real part is proved.Moreover,a new inequality of real part of α convex function of β is obtained.
