DESCRIPTION:Speakers: Lorenzo Ruffoni\n\nOberseminar Differentialgeometrie
 \nStrict hyperbolization is a procedure that turns a simplicial complex in
 to a space of negative curvature\, while preserving some topological featu
 res. It has been extensively used in the literature to produce examples of
  closed aspherical manifolds with exotic geometric features. In this talk\
 , I’ll describe this procedure with a focus on its relative version\, an
 d why it produces manifolds with residually finite fundamental groups. The
 n\, I'll discuss some more recent applications to the construction of Riem
 annian manifolds that are very far away from the world of locally symmetri
 c spaces\, and of topological manifolds that may not be virtually triangul
 able. This is joint work with J.-F. Lafont.\n \n \n \n\nhttps://math-ev
