Superrigidity for Irreducible Lattices and Geometric Splitting
نویسنده
چکیده
1.1. Superrigidity. In the early seventies, Margulis proved his celebrated superrigidity theorem for irreducible lattices in semisimple Lie and algebraic groups of higher rank. One of the motivations for this result is that it implies arithmeticity : a complete classification of higher rank lattices. In the case where the semisimple group is not almost simple, superrigidity reads as follows (see [M1], page 2):

Arithmeticity vs. Non-linearity for Irreducible Lattices
We establish an arithmeticity vs. non-linearity alternative for irreducible lattices in suitable product groups, for instance products of topologically simple groups. This applies notably to a (large class of) Kac-Moody groups. The alternative relies heavily on the superrigidity theorem we propose in [Md], since we follow Margulis’ reduction of arithmeticity to superrigidity.

We prove several superrigidity results for isometric actions on metric spaces satisfying some convexity properties. First, we extend some recent theorems of N. Monod on uniform and certain non-uniform irreducible lattices in products of locally compact groups. Second, we include the proof of an unpublished result on commensurability superrigidity due to Margulis. The proofs rely on certain noti...

متن کاملSuperrigidity, Weyl Groups, and Actions on the Circle
We propose a new approach to superrigidity phenomena and implement it for lattice representations and measurable cocycles with Homeo+(S ) as the target group. We are motivated by Ghys’ theorem stating that any representation ̺ : Γ → Homeo+(S ) of an irreducible lattices Γ in semi-simple real Lie groups G of higher rank, either has a finite orbit or, up to a semiconjugacy, extends to G which acts...
