On property (T) for $Aut (F_{n})$ and $SL_{n} (Z)$

Marek Kaluba, Dawid Kielak, Piotr W. Nowak

We prove that $Aut (F_{n})$ has Kazhdan's property (T) for every $n ⩾ 6$ . Together with a previous result of Kaluba, Nowak, and Ozawa, this gives the same state…

Singular subgroups in $A ~_{2}$ -groups and their von Neumann algebras

Yongle Jiang, Piotr W. Nowak

We show that certain amenable subgroups inside $A ~_{2}$ -groups are singular in the sense of Boutonnet and Carderi. This gives a new family of examples of singular group von Ne…

Expanders are counterexamples to the $ℓ^{p}$ coarse Baum-Connes conjecture

Yeong Chyuan Chung, Piotr W. Nowak

We consider an $ℓ^{p}$ coarse Baum-Connes assembly map for $1 < p < \infty$ , and show that it is not surjective for expanders arising from residually finite hyperbolic groups.
