多叶函数的某些性质

Some Properties of Certain Multivalent Functions

设A（p）表示形如f（z）在单位圆盘内解析函数全体，本文讨论了，推广了OwaS的结果．

Let A(p)denote the class of functions of the form f(z) =which are analytic in the unit disk U= .A Subclass Rp(a) of analytic fraction in U satisfying Ref(p)(z) > a for some a<p and all zU is introduced Our man result is the improvement of the former results Which were given by S.Owa.
