DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SiN/5/">When
  is a piecewise (a.k.a topological) full group locally compact?</a>\nby Al
 ejandra Garrido (Universidad Autónoma de Madrid) as part of Symmetry in N
 ewcastle\n\n\nAbstract\nQuestion: When is a piecewise (a.k.a topological) 
 full group locally compact? \n\nAnswer: Only when it's an ample group in t
 he sense of Krieger (in particular\, discrete\, countable and locally fini
 te) and has a Bratteli diagram satisfying certain conditions. \n\nComplain
 t: Wait\, isn't Neretin's group a non-discrete\, locally compact\, topolog
 ical full group? \n\nRetort: It is\, but you need to use the correct topol
 ogy!\n\nA fleshed-out version of the above conversation will be given in t
 he talk. Based on joint work with Colin Reid.\n
