Title: Frictionless thermostats and intensive constants of motion

Abstract: Thermostats models in space dimension $d=1,2,3$ for
 nonequilibrium statistical mechanics are considered and it is shown
 that, in the thermodynamic limit, the evolutions admit infinitely
 many constants of motion: namely the intensive observables.
