DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/123/"
 >Complex hyperbolic and projective deformations of Kleinian groups</a>\nby
  Julien Paupert (Arizona State) as part of CRM - Séminaire du CIRGET / G
 éométrie et Topologie\n\nLecture held in PK-5115.\n\nAbstract\nWe consid
 er deformations of discrete subgroups (in particular lattices) of SO(3\,1)
  into the larger Lie groups SU(3\,1) and SL(4\,R). In particular\, when su
 ch deformations exist we would like to know whether or not they remain dis
 crete and faithful in some neighborhood of the inclusion. We will review r
 esults of Cooper-Long-Thistlethwaite and Ballas-Danciger-Lee in the manifo
 ld case\, then discuss recent joint work with Morwen Thistlethwaite for ce
 rtain Bianchi groups.\n
