摘要
利用一类普通算子定义单位圆盘U内的双单叶解析函数类MN^h,pΣ(λ,μ;m,δ),并研究它的泰勒展式中第2项与第3项系数的估计结果,推广了众多已知文献的结论.
In this paper, a familiar subclass M N h,p Σ(λ,μ;m,δ) of analytic and bi-univalent functions in the open unit disk U defined by a general differential operator are introduced and investigated. Estimates for the second and third coefficients of their Taylor expansion are obtained. Some relevant connections of the result presented here with various well-known results are briefly indicated.
