摘要

The main aim of this paper is to introduce and investigate a new subclass of multivalent functions in the open unit disc U which is defined by a generalized Al-Oboudi differential operator. Coefficient inequalities, extreme points, Hadamard product and integral mean inequalities for fractional derivative of functions in this class are given.
