Abstract

Abstract. Let f denote a mapping from an orthogonality space (X;?) into a real Ba- nach space Y. In this paper, we prove the Hyers–Ulam stability of the orthogonally cubic functional equations f(2x+y)+f(2x¡y) = 2f(x+y)+2f(x¡y)+12f(x) and f(x+y+ 2z)+f(x+y¡2z)+f(2x)+f(2y) = 2f(x+y)+4f(x+z)+4f(x¡z)+4f(y+z)+4f(y¡z), where x ? y; y ? z; x ? z.
