Abstract

We introduce some classes of analytic functions, its subclasses and obtain sharp upper bounds of the functional |a_3-?a_2^2 | for the analytic function f(z)= z+ ?_(n=2)^??a_n z^n,|z|<1 belonging to these classes and subclasses.

Keywords

Univalent functions, Starlike functions, Close to convex functions and bounded functions, Closed functions, FeketeSzego inequality, Subordination method, Extremal function.
