DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSUGGT/1/">O
 n Finitely Presented Groups that Contain Q</a>\nby Jim Belk (University of
  St Andrews) as part of Ohio State Topology and Geometric Group Theory Sem
 inar\n\n\nAbstract\nIt is a consequence of Higman's embedding theorem that
  the additive group Q of rational numbers can be embedded into a finitely 
 presented group. Though Higman's proof is constructive\, the resulting gro
 up presentation would be very large and ungainly. In 1999\, Martin Bridson
  and Pierre de la Harpe asked for an explicit and "natural" example of a f
 initely presented group that contains an embedded copy of Q. In this talk\
 , we describe some solutions to this problem related to Thompson's groups 
 F\, T\, and V\, including a new simple group of type F infinity that conta
 ins Q. This is joint work with James Hyde and Francesco Matucci.\n
