DESCRIPTION:Title: <a href="https://stable.researchseminars.org/talk/SiN/5
 /">When is a piecewise (a.k.a topological) full group locally compact?</a>
 \nby Alejandra Garrido (Universidad Autónoma de Madrid) as part of Symmet
 ry in Newcastle\n\n\nAbstract\nQuestion: When is a piecewise (a.k.a topolo
 gical) full group locally compact? \n\nAnswer: Only when it's an ample gro
 up in the sense of Krieger (in particular\, discrete\, countable and local
 ly finite) and has a Bratteli diagram satisfying certain conditions. \n\nC
 omplaint: Wait\, isn't Neretin's group a non-discrete\, locally compact\, 
 topological full group? \n\nRetort: It is\, but you need to use the correc
 t topology!\n\nA fleshed-out version of the above conversation will be giv
 en in the talk. Based on joint work with Colin Reid.\n
