Abstract

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