DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/112/">H
 yperbolic subgroups of type FP_2(Ring)</a>\nby Shaked Bader (Oxford) as pa
 rt of Geometry and topology online\n\nLecture held in Room B3.02 in the Ze
 eman Building\, University of Warwick.\n\nAbstract\nIn 1996 Gersten proved
  that if $G$ is a word hyperbolic group of cohomological dimension two and
  $H$ is a subgroup of type $\\mathrm{FP}_2$\, then $H$ is hyperbolic as we
 ll.  I will generalise this result to show that the same is true if $G$ is
  only assumed to have cohomological dimension two over some ring $R$ and $
 H$ is of type $\\mathrm{FP}_2(R)$.\n\nThis is joint work with Robert Kroph
 oller and Vlad Vankov.\n
