Copyright policy )Second Hankel Determinant for a Certain Subclass of Bi-Close to Convex Functions Defined by Kaplan
In this paper, we consider the class of strongly bi-close-to-convex functions of order α and bi-close-to-convex functions of order β. We obtain an upper bound estimate for the second Hankel determinant for functions belonging to these classes. The results in this article improve some earlier result obtained for the class of bi-convex functions.
