Coefficient Estimates for a Subclass of Univalent Functions with Respect to Symmetric Points

Let A be the class of functions which are analytic in the open unit disc. We denote by S the subclass of A consisting of all functions in A which are also univalent in D. In this paper, the subclasses of S denoted by Cs(g) and K*s(g) are introduced. We obtain coefficient bounds for f element of Cs(g) and f element of K*s(g). These results generalize many known results.
