Abstract

Let S be the class of functions which are analytic, normalised and univalent in the open unit disc D = {z : |z| < 1}. In [4], Janteng introduced a subclass of close-to-convex functions with respect to (w.r.t) symmetric points denoted by Ks(α), 0 ≤ α < 1. In this paper, we give the upper bound for the second Hankel determinant for this particular class of functions.
