Abstract: The description of the temporal evolution of some physical systems is tackled from an information theory view-point in which Tsallis' entropy is extremalized with the constraints posed by the knowledge of the generalized expectation values of a selected set of observables. The concomitant Tsallis density operator is shown to be a particular solution of von Neumann's equation and Tsallis' entropy is seen to provide one with a constant of the motion. The pertinent ideas are illustrated with reference to the Larmor precession.
