Class of Harmonic Functions Defined by Differential Operator

Complex-valued harmonic functions that are univalent and sense preserving in the open unit disk can be written in the form f = h+g, where h and g are analytic.In this paper, we introduce and study a new subclass of harmonic univalent functions defined by differential operator.We give sufficient coefficient conditions for this class. By using extreme points theory we also obtain necessary and sufficient convolution conditions, coefficients estimates and integral mean inequalities for this class of functions.
