摘要
We define an antiderivation from an algebra A into an A-imodule M as a linear map delta : A --> M such that delta(ab) = delta(b)a + bdelta(a) for all a, b is an element of A. The main result states that every Jordan derivation from the algebra of all upper triangular matrices into its bimodule is the sum of a derivation and an antiderivation. (C) 2004 Elsevier Inc.
