Abstract

We introduce a new class of analytic functions and its subclasses and obtain 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.

Keywords

Bounded functions, Inverse Starlike functions, Starlike functions and Univalent functions, Complex functions, Principle of Subordination, Coefficient inequality, Extremal functions.
