DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/94/">Qu
 asi-flats in the Aut free factor complex</a>\nby Richard Wade (University 
 of Oxford) as part of Geometry and topology online\n\nLecture held in Room
  B3.02 in the Zeeman Building\, University of Warwick.\n\nAbstract\nWe wil
 l describe families of quasi-flats in the "$\\mathrm{Aut}(F_n)$ version" o
 f the free factor complex. This shows that\, unlike its more popular "Oute
 r" cousin\, the $\\mathrm{Aut}$ free factor complex is not hyperbolic. The
  flats are reasonably simple to describe and are shown to be q.i. embedded
  via the construction of a coarse Lipschitz retraction. This leaves many o
 pen problems about the coarse geometry of this space\, and I hope to talk 
 about a few of them. \n\nThis is joint work with Mladen Bestvina and Marti
 n Bridson.\n
