A new class of univalent functions is de ned by making use of the Ruscheweyh derivatives. We provide necessary and sufficient coefficient conditions, extreme points, integral representations, distortion bounds, and radius of starlikeness and convexity for this class.
Keywords: analytic, univalent, convex, starlike, ruscheweyh derivative
