Superrigidity, arithmeticity, normal subgroups: results, ramifications and directions
arXiv:2003.02956
Abstract
This essay points to many of the interesting ramifications of Margulis' arithmeticity theorem, the superrigidity theorem, and normal subgroup theorem. We provide some history and background, but the main goal is to point to interesting open questions that stem directly or indirectly from Margulis' work and it's antecedents.
