Abstract:
 The object of the present papaer is to derive various interesting properties of a certain subclass of starlike functions with negative coefficients. In particular, we give numerous sharp results including coefficient estimates, distortion theorem and radius of convexity for functions belonging to this subclass. We also show that the class studied in this work is closed under arithmetic mean and convex linear combinations. Furthermore, integral operator of several functions belonging to the class T*(l, g) (A, B, α, β, p) are studied here.
