Some Results on Janowski Close to Convex Mappings

Melike Aydo˜gan

Let JC(A, B) denote the class of functions φ(z) = z + P∞ k=2 akz k are analytic in the open unit disc D such that zφ 0 (z) s(z) ≺ 1 + Az 1 + Bz , −1 ≤ B < A ≤ 1  where s(z) = z + P∞ k=2 bkz k is convex in D. In this paper we determine the coefficient estimates distortion theorems for this class.
