Title: A tour through the proof of Margulis Superrigidity
Abstract: Margulis' Superrigidity theorem tells us that for a higher rank semisimple Lie group G, any representation of a lattice extends to a continuous representation of G (under reasonably mild conditions). In this talk, we'll go through a proof of this fact, and along the way see how this proof combines ideas from Lie theory, dynamics, and random walks on groups. In particular, we'll see how a stationary measure on G/P is constructed, and combine that with measure proximality to prove Margulis Superrigidity.
