New Applications of Faber Polynomial Expansion for Analytical Bi-Close-to-Convex Functions Defined by Using q-Calculus

In this investigation, the q-difference operator and S?l?gean q-differential are utilized to establish novel subclasses of analytical bi-close-to-convex functions. We determine general Taylor–Maclaurin coefficient functions in class using Faber polynomial method. demonstrate unpredictable behaviour initial coefficients a2, a3 investigate Fekete–Szeg? problem a3?a22 for To highlight connections between existing knowledge new research, certain known unknown corollaries also highlighted.
