doi:10.3906/mat-0809-36 A perturbation of m-order derivations on Banach algebras Yong-Soo Jung ∗ and Kyoo-Hong Park Let A be a unital Banach algebra and let m, 1 ≤ m ≤ 4, be an integer. If f: A → A is an approximate m-order derivation in the sense of Hyers-Ulam-Rassias, then f: A → A is an exact m-order derivation
