The objective of this paper is to obtain sharp upper bound to the second Hankel functional associated with the root transform of normalized analytic function belonging to parabolic starlike and uniformly convex functions, defined on the open unit disc in the complex plane, using Toeplitz determinants.
Mots clés : Analytic function, parabolic starlike and uniformly convex functions, upper bound, second Hankel functional, positive real function, Toeplitz determinants.
