In this paper we introduce and study some new subclasses of starlike, convex, close-to-convex and quasi-convex functions defined by the Komatu integral operator. Inclusion relationships are established and integral operator of functions in these subclasses is discussed. 相似文献

By making use of a general linear operator , the authors introduce several new subclasses of multivalent functions and investigate various inclusion relationships and argument properties associated with these subclasses. Some interesting applications involving such and other families of linear operators are also considered. The results presented here include a number of known results as their special cases. 相似文献

Cauchy-Stieltjes积分和面积平均p叶函数 总被引:1,自引:0,他引:1
本文研究由Cauchy-Stieltjes积分形成的函数空间Fα.首先给出这个空间的一个等价定义,然后研究面积平均p叶函数的对数函数和这个函数空间的关系,最后对单叶函数的情形做进一步的讨论.根据这种研究,我们得到了有界单叶函数的系数增长估计,这是目前最好的结果. 相似文献

Briot-Bouquet differential subordinations play a prominent role in the theory of differential subordinations. In this article we consider the dual problem of Briot-Bouquet differential superordinations. Let β and γ be complex numbers, and let Ω be any set in the complex plane C. The function p analytic in the unit disk U is said to be a solution of the Briot-Bouquet differential superordination if
