초록

In this paper, we prove the Hyers-Ulam-Rassias stability of the following functional equation f(x + y + z) + f(x y + z) + f(x + y z) + f( x + y + z) = 4 f(x) + 4 f(y) + 4 f(z) on the whole space. Moreover, the Hyers-Ulam stability of that equation will also be investigated for functions defined on a restricted domain.
