DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/65/">St
 rict hypbolisation and special cubulation</a>\nby Lorenzo Ruffoni (Tufts) 
 as part of Geometry and topology online\n\n\nAbstract\n<p>\n        Gromov
  introduced some "hyperbolisation"\n        procedures that turn a given p
 olyhedron into a space of\n        non-positive curvature.  Charney and Da
 vis developed a refined\n        "strict hyperbolisation" procedure that o
 utputs a space of\n        strictly negative curvature.  Their procedure h
 as been used to\n        construct new examples of manifolds and groups wi
 th negative\n        curvature\, and other prescribed features. We constru
 ct actions\n        of the resulting groups on CAT(0) cube complexes.  As 
 an\n        application\, we obtain that they are virtually special\, henc
 e\n        linear over the integers and residually finite.\n      </p>\n  
     <p>\n        This is joint work with J. Lafont.\n      </p>\n
