Abstract

In this paper we use the principle of subordination between analyticfunctions and the convolution to introduce the class S~(f,g;A,B;α,β).We obtain coefficient inequalities, distortion theorems, extreme points, radii of close to convexity,starlikeness and convexity for this class and modified Hadamard product ofseveral functions belonging to it. Also, we investigate several distortion inequalities involvingfractional calculus. Finally, we obtain integral means for functionsbelonging to this class.
