Certain Coefficient Problems of $\mathcal{S}_{e}^{*}$ and $\mathcal{C}_{e}$

Complex Variables 2023-09-07 v2

Abstract

In this current study, we consider the classes Se\mathcal{S}^{*}_{e} and Ce\mathcal{C}_e to obtain sharp bounds for the third Hankel determinant for functions within these classes. Additionally, we provide estimates for the sixth and seventh coefficients while establishing the fourth-order Hankel determinant as well.
