Journal ArticleDOI
Property (T) and rigidity for actions on Banach spaces
TL;DR: For simple Lie groups and their lattices, this paper showed that the fixed point property for Lp holds for any 1 < p < ∞ if and only if the rank is at least two.

On the growth of $L^2$-invariants for sequences of lattices in Lie groups
Miklós Abért,Nicolas Bergeron,Ian Biringer,Tsachik Gelander,Nikolay Nikolov,Jean Raimbault,Iddo Samet +6 more
TL;DR: In this paper, the authors study the asymptotic behavior of Betti numbers, twisted torsion and other spectral invariants of sequences of locally symmetric spaces and show that BS-convergence implies convergence, in an appropriate sense, of the associated normalized relative Plancherel measures.
Journal ArticleDOI
On dense free subgroups of Lie groups
TL;DR: In this article, Carriere and Ghys gave an elementary proof to a conjecture of Connes and Sullivan on amenable actions, which was first proved by Zimmer in the context of real Lie groups.

TL;DR: In this article, the authors studied the asymptotic behavior of Betti numbers, twisted torsion and other spectral invariants of sequences of locally symmetric spaces and showed that BS-convergence implies convergence of normalized relative Plancherel measures associated to L 2 (Γ\G).
