A Fixed Point Approach to the Stability of a Nonic Functional Equation in Modular Spaces
Authors: , ,
Abstract: In this paper, we present a fixed point results which was proved by Khamsi [9] in modular function spaces to prove the generalized Hyers-Ulam stability of a nonic functional equation : f(x+5y) - 9f(x+4y) + 36f(x+3y) - 84f(x+2y) + 126f(x+y) - 126f(x) + 84f(x-y)-36f(x-2y)+9f(x-3y)-f(x-4y)= 9 ! f(y), where 9 ! = 362880 in modular spaces.
