A mixing property for the action of $\SL(3,\mathbb{Z})\times\SL(3,\mathbb{Z})$ on the Stone-Cech boundary of $\SL(3,\mathbb{Z})$

An example of a non-amenable dynamical system which is boundary amenable
Jacopo Bassi, Florin Radulescu
It is shown that the action of on the Stone-uCech boundary of is amenable. This confirms a prediction by…
