Introduction to weak Pinsker filtrations
Séverin Benzoni
We introduce the so-called weak Pinsker dynamical filtrations, whose existence in any ergodic system follows from the universality of the weak Pinsker property, recently proved by…

Confined Poisson extensions
Séverin Benzoni, Emmanuel Roy, Thierry de la Rue
This paper follows on from our previous work, where we introduced the notion of \emph{confined extensions}, and our purpose is to widen the context in which such extensions appear.…

Confined extensions and non-standard dynamical filtrations
Séverin Benzoni
In this paper, we explore various ways in which a factor -algebra can sit in a dynamical system , i.e. we study some possible…
