Abstract
Recently, Acu and Owa [1] further studied the work of Kanas and Ronning [2] by investigating the classes of close - to - convex and α- convex functions normalised with f(w) = f (w)-1 = 0 and w is a fixed point in E. Ghanim and Darus introduced another subclass using the fixed point. Necessary and sufficient conditions were provided for this class. The aim of this paper is to continue the investigation by extending this class of functions to the class Sn(α) defined by the Salagean [4], our result extends some existing ones and new ones are derived.
