Abstract

Let SH denote the class of functions =fhg+ which are harmonic univalent and sense preserving in the unit disk U. Earlier we have introduced a class of harmonic functions defined by a generalised differential operator. In this paper we introduce a new subclass of this class and obtain results on coefficient bounds, distortion and extreme points.
