In the present article, an upper bound for third order Hankel determinant H-3 (1) is obtained for a certain subclass of univalent functions generated by Ruscheweyh derivative operator.eninfo:eu-repo/semantics/closedAccessunivalent functionsHankel determinantToeplitz determinantRuscheweyh derivativeUPPER BOUND ON THE THIRD HANKEL DETERMINANT FOR FUNCTIONS DEFINED BY RUSCHEWEYH DERIVATIVE OPERATORArticle10.4134/CKMS.c1700812-s2.0-850459109494442Q343733WOS:000431396000006N/A
