Abstract
In this paper, a new class of harmonic univalent functions was defined by the differential operator. We obtained some geometric properties, such as the coefficient estimates, convex combination, extreme points, and convolution (Hadamard product), which are required
Highlights
A complex - valued continuous harmonic function f = u + iv is harmonic in whether both u and v are real harmonic, at any connected which may be written as f = h + ̅, where h and g are analytic in .We call "h” analytic part and " " co-analytic part of f
Wherever h and g are given by h(z) = z - ∑ | |, (z) =
Many authors studied the family of harmonic univalent function
