DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CIRGET/158/"
 >Strict hyperbolization of flat manifolds</a>\nby Mauricio Bustamente (UQA
 M) as part of CRM - Séminaire du CIRGET / Géométrie et Topologie\n\nLec
 ture held in PK-5115.\n\nAbstract\nCharney–Davis strict hyperbolization 
 is a construction that takes a nonpositively curved cube complex and conve
 rts it into a negatively curved space. In this talk\, I’ll explain how s
 trict hyperbolization can be used to produce closed hyperbolic manifolds w
 ith interesting topological features\, by applying it to a suitable class 
 of flat manifolds. This leads to new examples of closed hyperbolic manifol
 ds with nontrivial Pontryagin and Stiefel–Whitney classes\, hyperbolic m
 anifolds that arise as totally geodesic boundaries of other hyperbolic man
 ifolds\, and aspherical topological manifolds that admit no smooth structu
 re. This is joint work with Eduardo Reyes and Stefano Riolo.\n
