Apparaît dans la collection : 2022 - T2 - WS2 - Self-similarity of groups, trees and fractals

We discuss the notion of "tight inclusion" of dynamical systems which is meant to capture a certain tension between topological dynamics and ergodic theory (especially in the context of "boundary actions"). The level of abstraction we consider is wide enough to include results regarding unitary representations.

Joint work with Mehrdad Kalantar.
