Abstract

Given a measure μ on the circle, we study the relations between the entropy of the multiplication by an integerp and the conservativity for the translations by thep-acid rational numbers. We get a criterium for μ-almost every point to be normal in a basisq prime top, and generalizations of the result of D. Rudolph about measures which are invariant by multiplication byp andq.
