A complete characterization of connected Lie groups with the Approximation Property

Uffe Haagerup, Søren Knudby, Tim de Laat

We give a complete characterization of connected Lie groups with the Approximation Property for groups (AP). To this end, we introduce a strengthening of property (T), that we call…

Approximation properties for noncommutative $L^{p}$ -spaces of high rank lattices and nonembeddability of expanders

Tim de Laat, Mikael de la Salle

This article contains two rigidity type results for $SL (n, Z)$ for large $n$ that share the same proof. Firstly, we prove that for every $p \in [1, \infty]$ differe…

Strong property (T) for higher rank simple Lie groups

Tim de Laat, Mikael de la Salle

We prove that connected higher rank simple Lie groups have Lafforgue's strong property (T) with respect to a certain class of Banach spaces $E_{10}$ containing many class…
