Abstract
Si prova con strumenti elementari che esiste una massa invariante rispetto ad una arbitraria famiglia commutante di trasformazioni su un insieme qualunque.
We prove by means of very elementary tools the existence of a finitely additive probability invariant under the elements of a commuting family of transformations.
