Inverse Coefficient Bounds for Bounded Turning Functions in the CardioidDomain

The primary aim of this article is to obtain the constraints for specific inverse initial coefficients for a subclass of bounded turning functions, which are associated with the cardioid domain and are denoted by BT car. The study also focuses on Fekete-Szeg¨o inequality and the Hankel determinants of order two and three within a specific subclass of functions.
