Subject area: Science,Engineering and Technology · Area of research: Geometric Function Theory

Abstract

We introduce a class of analytic functions 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 this class with special character that it tends to the class of Starlike functions as PIE/2

Keywords

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