On a subclass of certain convex functions with negative coefficients. (English) Zbl 1101.30303
Summary: Coefficient, distortion, covering, and coefficient inequalities are determined for univalent functions with negative coefficients that is convex of order $$\alpha$$. Extreme points for this class is also determined.
