The Margulis Superrigidity Theorem

A lattice is a special kind of discrete subgroup of a topological group. The Margulis superrigidity theorem says, roughly, that if the group satisfies certain conditions then the structure of the lat-tice has a surprising amount of influence on the structure of the group. For this and related work, Grigory Margulis won the Fields Medal in 1978. I’ll try to present some of these ideas in a way un-derstandable to grad students of all backgrounds
