Hankel and Toeplitz determinants of logarithmic coefficients of Inverse functions for certain classes of univalent functions
Sanju Mandal, Partha Pratim Roy, Molla Basir Ahamed
The Hankel and Toeplitz determinants and are defined as: \begin{align*} H_{2,1}(F_{f^{-1}}/2):= \begin{vmatrix} Γ_1 & Γ_2 Γ_2 & Γ_3…

The third Hankel determinant for inverse coefficients of starlike functions of order 1/2
Molla Basir Ahamed, Partha Pratim Roy
The sharp bound for the third Hankel determinant for the coefficients of the inverse function of starlike function of order is obtained. In light of this, we can deduce that…

Sharp bounds for second Hankel determinant of logarithmic coefficients for certain classes of univalent functions
Sanju Mandal, Partha Pratim Roy, Molla Basir Ahamed
The Hankel determinant is defined as: \begin{align*} H_{2,2}(F_{f}/2):= \begin{vmatrix} γ_2 & γ_3 γ_3 & γ_4 \end{vmatrix}, \end{align*} where and $γ_…
