- ItemUpper Bounds for Fekete-Szego functions and the Second Hankel Determinant for a Class of Starlike functions(2017-04-30) Bello R. A.; Opoola T. O.In this work,we provide upper estimate for Fekete-Szego functional and Second Hankel determinant for the class šā{š} consisting of functions analytic in the unit disk U = {zā C : |z| < 1} and normalized by f (0) =šā² (0) = 1 = 0 and which satisfies the subordination condition
