A SUBFAMILY OF BI-UNIVALENT FUNCTIONS INVOLVING THE RIEMANN{LIOUVILLE FRACTIONAL DERIVATIVE SUBORDINATE TO THE SINE FUNCTION
In this study, we provide a class of bi-univalent functions de ned
via the Riemann{Liouville subordination derivative with the sine function. we
establish that this class is non-empty and provide best bounds for the initial
coefficients, alongside the maximal estimate for the Fekete-Szego functional.
