Abstract

Abstract : We examine the generalized Hyers-Ulam stability of the following functional equation: 2 f x + y + z + w + f - x - y + z + w + f - x + y - z + w + f - x + y + z - w + f x - y - z + w + f x - y + z - w + f x + y - z - w - 5 f x - 3 f - x - 5 f y - 3 f - y - 5 f z - 3 f - z - 5 f w - 3 f - w = 0, in the fuzzy normed spaces with the fixed point method.
