Abstract
A sufficient condition for the existence of an invariant measure is given that is useful in number theory. A connection with a problem of Blum is pointed out. Kuzmin's theorem is considered from an operator point of view, and the Chacon-Ornstein theorem is applied to give almost everywhere Cesaro convergence to the density of the invariant measure.
