DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/SiN/9
 /">Quantitative LEF and topological full groups</a>\nby Henry Bradford (Un
 iversity of Cambridge) as part of Symmetry in Newcastle\n\n\nAbstract\nTop
 ological full groups of minimal subshifts are an important source of exoti
 c examples in geometric group theory\, as well as being powerful invariant
 s of symbolic dynamical systems. In 2011\, Grigorchuk and Medynets proved 
 that TFGs are LEF\, that is\, every finite subset of the multiplication ta
 ble occurs in the multiplication table of some finite group. In this talk 
 we explore some ways in which asymptotic properties of the finite groups w
 hich occur reflect asymptotic properties of the associated subshift. Joint
  work with Daniele Dona.\n
