Abstract
Using the direct method and fixed point method, we investigate the Hyers-Ulam
stability of the following cubic ?-functional equation f(x+2y) + f(x-2y)- 2f(x+y)-2f(x-y)-12f(x) = ?(4f(x+y/2) + 4f(x-y/2)-f(x+y)-f(x-y)-6f(x)) in matrix non-Archimedean
random normed spaces, where ? is a fixed real number with ? ? 2.
