Upper Bound of Second Hankel Determinant for Certain Subclasses of Analytic Functions
In this present investigation, we first give a survey of the work done so far in this area of Hankel determinant for univalent functions. Then the upper bounds of the second Hankel determinant |a2a4−a32| for functions belonging to the subclasses S(α,β), K(α,β), Ss∗(α,β), and Ks(α,β) of analytic fu...
