Hankel determinant of type $H_{2}(3)$ for inverse functions of some classes of univalent functions with missing second coefficient

Abstract

In this paper we determine the upper bounds of $|H_{2}(3)|$ for the inverse functions of functions of some classes of univalent functions, where $H_{2}(3)(f)=a_{3}a_{5}-a_{4}^{2}$ is the Hankel determinant of a special type.
