关于Re[e^(iα)Z·f′(z)/f(z)]>β的螺象函数

Oo Re[ e^(iα) z ·f'(z)/f(z)]>β Sprialke Function

本文研究α-螺象函数族S(a)的子族S(α,β),0≤β<1的性质,得到了S(α,β)中函数的积分表达式,偏差定理,旋转定理、模数和系数的估计,并证明了极值函数的唯一性定理。

In this peper we have stndied the classes of functions S(α.β)={f: f(Z)∈S;and got their integral expressiens deviation peroprtics、 and calculations of module and ccefficierts of functicns in S( XXX·BBB) we have proved aloneproperth of an mctremal function and expanded some results of [2]-[4]、 and rePlenished the absence in [5]
