    Certain subclasses of bi-univalent functions related to k-Fibonacci numbers
    (Ankara Üniversitesi Fen Fakültesi, 2019-08-01) Güney, Özlem H.; Murugusundaramoorthy, G.; Sokol, Janusz; Other; Other
    In this paper, we introduce and investigate new subclasses of bi-univalent functions related to k-Fibonacci numbers. Furthermore, we nd estimates of first two coecients of functions in these classes. Also, we obtain the Fekete-Szego inequalities for these function classes.
