Abstract

Let ℋ denote the class of functions f which are harmonic and univalent in the open unit disc D = {z : \z\<1}.This paper defines and investigates a family of complex-valued harmonic functions that are orientation preserving and univalent in D and are related to the functions convex of order β(0 β< β < 1), with respect to symmetric points. We obtain coefficient conditions, growth result, extreme points, convolution and convex combinations for the above harmonic functions.
