A subclass of harmonic univalent functions with positive coefficients associated with fractional calculus operator

Abstract

In the present paper, we are defining a subclass of harmonic univalent functions with positive coefficients in unit disc $U$ by using fractional calculus operator. Further we obtain distortion bounds, extreme points and radii of convexity for functions belonging to this class and discuss a class preserving integral operator. Here we also determine that the class studied in this paper is closed under convolution and convex combinations.
