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

In the present paper, we are defining a subclass of harmonic univalent functions with positive coefficients in unit disc 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.
