摘要：Let A be a unital Banach algebra and M be a unital A-bimodule. We show that if is a linear mapping from A into M satisfying (ST) = (S)T +S(T) for any S, T A with ST = W, where W is a left or right separating point of M, then is a Jordan derivation. Also, it is shown that every linear mapping h from A into a unital Banach algebra B which satisfies h(S)h(T) = h(ST) for any S, T A with ST = W is a Jordan homomorphism if h(W) is a separating point of B.
