On a New Subclass of Univalent Functions with Positive Coefficients Defined by Ruscheweyh Derivative
In this paper, we have discussed a subclass N(α,δ,β,λ) of analytic and univalent functions with positive coefficients defined by Ruscheweyh derivative in unit disk C={z∈C∶ |z|<1}. We obtain basic properties like coefficient inequality, distortion theorem, extreme points, radii of starlikeness, convexity and close-to-convexity and neighborhoods.
