Hankel Determinants of Logarithmic Coefficients for the Class of Bounded Turning Functions Associated with Cardioid Domain

In this study, we initially established bounds for the logarithmic coefficients concerning a specific subclass of bounded turning functions R_℘ that are linked to the cardioid domain. For the functions belonging to this class, we identified sharp bounds for the second Hankel determinant of logarithmic coefficients, denoted as H_2,1 (F_f \/2). In conclusion, we computed the bounds of the third Hankel determinant of logarithmic coefficients H_3,1 (F_f \/2).
