Abstract

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


Keywords

Univalent functions, Starlike functions, Close to convex functions and bounded functions
