Subclass of Starlike functions of complex order defined by a generalized Srivastava –Attiya operator

Abstract

The main object of this paper is to study some properties of certain subclass of starlike functions of complex order with negative coefficients denoted by  defined by a general  integral operator in the open unit disc  and investigate its various characteristics.  Further, we obtain coefficient inequalities, extreme points, growth and distortion property and radii of close-to-convexity, starlikeness and convexity for functions belonging to the subclass
