Jun 28, 2014 at 14:21 comment added Misha Right. You do not need to assume existence of cusps to get rigidity in their setting; but if you do allow cusps, then you have to assume that they stay unipotent under deformations.
Jun 28, 2014 at 10:50 comment added ThiKu Thanks a lot. I guess a similar argument applies for n>2 (at least for manifolds with cusps) in view of the <a href="ambp.cedram.org/cedram-bin/article/… rigidity result of Porti and Menal-Ferrer</a>
Jun 28, 2014 at 10:37 comment added Misha Yes, by local rigidity.
Jun 28, 2014 at 8:27 comment added ThiKu Is it known whether this zero volume representations belong to distinct components?
