On a Subclass of Certain Convex Harmonic Univalent Functions Related to Q-Derivative

Abstract

We define and investigate a new class of harmonic functions defined by q -derivative We give univalence criteria and sufficient coefficient conditions for normalized q -harmonic functions that are convex of order b 0 _ b 1 We obtain coefficient inequalities extreme points distortion bounds convolution and convex combination condition and covering theorems for these functions Further we obtain the closure property of this class under integral operator
