Abstract

The aim of the present paper is to investigate a new subclass of starlike functions of complex order . Let be an analytic function in the unit disc which satisfies , for some and for all . Then f is called a Janowski starlike function of complex order b, where A and B are complex numbers such that , and . The class of these functions is denoted by . In this paper we will give the representation theorem, distortion theorem, two point distortion theorem, Koebe domain under the montel normalization, and coefficient inequality for this class.
