算子D^α及其刻划的∑p函数类

Operator D^α and some subclasses of meromorphic p-valet functions

用算子Dα刻划亚纯星象函数、亚纯凸象函数、亚纯近于凸函数和亚纯拟凸函数的新子类,建立包含关系,讨论类中函数积分算子的性质。

In this paper we introduce and study some new subclasses of meromorphic univalent functions defined by operator. Inclusion relations are established and ir.tegral operator of functions in these subclasses are discussed.
