In this talk, I will introduce the class of geodesically rich
representations. These are representations of (real or complex)
hyperbolic lattices that preserve a significant amount of the
geometric structure of the associated quotient manifold. When the
quotient manifold has robust geometric structure, these
representations exhibit rigidity phenomena. In particular, a recent
superrigidity theorem for rich representations was used to prove that
finite-volume hyperbolic manifolds with infinitely many maximal
totally geodesic submanifolds are arithmetic
(Bader-Fisher-Miller-Stover). I will discuss a new superrigidity
theorem for rich representations that efficiently recovers existing
results and addresses target groups that were previously inaccessible.
