Abstract :The aim of this paper is to give bounds of the radius of a -convexity for certain families of analytic functions in the unit disc. The radius of a -convexity is generalization of the radius of convexity and the radius of starlikeness, and introduced by S.S.Miller; P.T.Mocanu and M.O.Reade [3,4]Keywords : Subordination principle, Carathedory functions, Janowski Starlike functions, Starlike functions of order b, The radius of Starlikeness, The radius of convexity, The radius of a-convexity.
