چکیده

We consider the functional equation f(ax+y) + f(ax-y)-a(a+1)f(x)-a (a-1) f(-x) - [f(y)+f(-y)] + k[f(x+y) + f(x-y)-2f(x)- f(y) - f(- y)] = 0 for a fixed rational number a with a ≠ 1,- 1,0 and a fixed real number k. we study the solution of the equation between linear spaces and prove the generalized hyers-ulam stability for it when the target space is a fuzzy normed space. © 2014 chang il kim et al.
