A mixing property for the action of $\SL(3,\mathbb{Z})\times\SL(3,\mathbb{Z})$ on the Stone-Cech boundary of $\SL(3,\mathbb{Z})$
Jacopo Bassi, Florin Radulescu
By analogy with the construction of the Furstenberg boundary, the Stone-{\v C}ech boundary of $\SL(3,\mathbb{Z})$ is a fibered space over products of projective matrices. The proxi…
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…
Separable boundaries for non-hyperbolic groups
Jacopo Bassi, Florin Radulescu
We exhibit examples of separable boundaries for non-hyperbolic groups. The main ingredient is the alignment property introduced by Furman in the study of rigidity properties of dis…
Twisted Akemann-Ostrand property for and Ramanujan Petersson Conjectures
Florin Radulescu
We prove an extension of the Akemann - Ostrand theorem, regarding the simultaneous, left and right regular representations of the free group, modulo compact operators, to the case…
Endomorphisms of spaces of virtual vectors fixed by a discrete group
Florin Radulescu
Consider a unitary representation of a discrete group , which, when restricted to an almost normal subgroup , is of type II. We analyze the associated unitary…
On unbounded, non-trivial Hochschild cohomology in finite von Neumann algebras and higher order Berezin's quantization
Florin Radulescu
We introduce a class of densely defined, unbounded, 2-Hochschild cocycles ([PT]) on finite von Neumann algebras . Our cocycles admit a coboundary, determined by an unbounded ope…
