Abstract

Let U be a ϕ\phi -Johnson amenable Banach algebra in which ϕ\phi is a non-zero multiplicative linear functional on U. Suppose that X is a Banach U-bimodule such that a.x=ϕ(a)xa.x=\phi(a)x for all a in U and x in X or x.a=ϕ(a)xx.a=\phi(a)x for all a in U and x in X. We show that every continuous Jordan derivation from U to X is a derivation, and every continuous Lie derivation from U to X decomposed into the sum of a continuous derivation and a continuous center-valued trace.
