Zero Krengel Entropy does not kill Poisson Entropy
Résumé
The purpose of this article is to construct a conservative infinite-measure-preserving transformation with zero Krengel entropy (the induced transformation on a set of measure 1 is the Von Neumann-Kakutani odometer), but whose associated Poisson suspension has positive entropy.
