Let{αt:t∈R}and{βt:t∈R}be two commuting one-parameter groups of∗-automorphisms of a von Neumann algebraMsuch thatαt+α−t=βt+β−tfor allt∈R. The purpose of this note is to provide a simple and short proof of the central decomposition result:αt=βtonMpand aαt=β−tonM(1−p)for a central projectionp∈M, without using the theory of spectral subspaces.
