Here we describe some classes of analytic functions and its subclasses by which we will be obtaining sharp upper bounds of the functional |a_3-µa_2^2 | for the analytic function f(z)= z+ ?_(n=2)^??a_n z^n,|z|<1 belonging to these classes and subclasses.
Univalent functions, Starlike functions, Close to convex functions and bounded functions.
