关于解析函数的一个不等式 总被引:2,自引:0,他引:2
Let P(Z) = 1 + P1Z + P2Z2 +…be an analytic function in the unit disc D. In thispaper, we determine the value of φ(α,β) for which Re[P(Z) + αZP′(Z)] > β,Z ∈ D,α > 0,β < 1 implies that Re{P(Z)} >φ(α,β) for all Z ∈ D, and this result is sharp. Some of its interesting consequences are also given. In addition, we give a new univalence criterion. 相似文献
