On the third hankel determinant for a subclass of close-to-convex functions

Abstract

Let A denote the class of all normalized analytic function f in the unit disc U of the form (Formula presented.). The object of this paper is to obtain a bound to the third Hankel determinant denoted by H 3 (1) for a subclass of close-to-convex functions.
