 note = {application/pdf, In this note, we study (not necessarily ergodic) integrable systems on von Neumann algebras. As a generalization of A. Amann [1, Capter II, Theorem 2], we show that a ＄W*＄ -dynamical system ＄(m, G, a)＄ is integrable if and only if there is a normal covariant embedding of ＄L^{￥infty}(G)＄ into ＄(ffl, G, a)＄ .},
