Sufficient conditions for starlikeness related to a hyperbolic cosine function

Year: 2025

Type: article

Abstract: UDC 517.5 We determine sufficient conditions for functions to be in the class $\mathcal{S}^{*}_{\varrho}$ formed by starlike functions related to $\cosh \sqrt{z}$ by using the Briot–Bouquet and other differential subordination techniques. Additionally, in order to ensure the sharpness of our results, we include graphical validations and appropriate illustrations.
