Abstract :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.
Keywords : Analytic functions, bi univalent, k fibonacci numbers, starlike function, convex function
