Then, the coefficient estimates, the Fekete–Szegö problem, and the second-order Hankel determinant H2(1) for functions belonging to this class Rq(h) are investigated. Furthermore, similar results are examined and presented for the functions zf(z) and f−1(z). For the validity of our results, relevant connections with those in earlier works are also pointed out.enanalytic functionsunivalent functionsbounded turning functionsq-derivative (or q-difference) operatorprinciple of subordination between analytic functionsleaf-like domaincoefficient estimatesTaylor-Maclaurin coefficientsFekete–Szegö problemHankel determinantArticleDepartment of Mathematics and Statistics
