Let (A, R, σ) be an abelian C*-dynamical system. Denote the generator of σ by δ0 and define A = ∩n>1D0n). Further define the Lipschitz algebra .

If δ is a *-derivation from A into A½, then it follows that δ is closable, and its closure generates a strongly continuous one-parameter group of *-automorphisms of A. Related results for local dissipations are also discussed.
