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

On A Subclass of Harmonic Univalent Funtions Associated with the Differential Operator

“…Recently S. Porwal and Shivam Kumar [11] and A.L. Pathak et al [12] have defined and studied a subclass of harmonic univalent functions using differential operator. They have obtained the coefficient and distortion bounds, extreme points, convolution and convex combinations.…”

On a new subclass of harmonic univalent functions defined by multiplier transformation

“…After the appearence of this paper several researchers (e.g. see Pathak et al [10], Porwal and Aouf [12], Porwal et al [16]) generalized the result of [6] by using certain operator. Very recently Porwal and Dixit [13] (see also [14]) investigated new subclasses of harmonic starlike and convex functions.…”
