Abstract
The Hankel determinant of logarithmic coefficients is defined as: \begin{align*} H_{2,1}(F_{f^{-1}}/2):= \begin{vmatrix} \Gamma_1 & \Gamma_2 \Gamma_2 & \Gamma_3 \end{vmatrix}=\Gamma_1\Gamma_3-\Gamma^2_2, \end{align*} where and are the first, second and third logarithmic coefficients of inverse functions belonging to the class of normalized univalent functions. In this article, we establish sharp inequalities , , and for the logarithmic coefficients of inverse functions, considering starlike and convex functions, as well as functions with bounded turning of order , respectively.
