DESCRIPTION:Title: <a href="https://researchseminars.org/talk/MSR80/11/">A
 rithmeticity\, superrigidity and totally geodesic manifolds</a>\nby David 
 M. Fisher as part of International Conference on Discrete groups\, Geometr
 y and Arithmetic\n\n\nAbstract\nI will discuss recent results showing that
  a finite volume real or complex hyperbolic\nmanifold with infinitely many
  maximal totally geodesic submanifolds is arithmetic. The proof\nbrings to
 gether homogeneous dynamics and a new superrigidity theorem. [This is join
 t work with\nBader\, Miller and Stover.]\n
