DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/98/">Th
 e coherence of one-relator groups</a>\nby Marco Linton (Oxford) as part of
  Geometry and topology online\n\nLecture held in Room B3.02 in the Zeeman 
 Building\, University of Warwick.\n\nAbstract\nA group is 'coherent' if al
 l of its finitely generated subgroups are finitely presented.  In this tal
 k I will sketch a proof of Baumslag’s conjecture that all one-relator gr
 oups are coherent\, discussing connections with the non-positive immersion
 s property and the vanishing of the second L^2 Betti number.\n\nThis is jo
 int work with Andrei Jaikin-Zapirain.\n
