It is a known resul t that the box space having property A is equivalent to the group being am enable. The same is true for hyperfiniteness. Firstly we will optimise thi s result by replacing filtrations by Farber sequences and secondly determi ne which arrows still hold when we replace box spaces by sofic approximati ons.\n\nKnowledge of the above concepts is not required since these will b e introduced during the talk.\n DTSTART:20180509T200000Z DTEND:20180509T210000Z LOCATION:Room 920\, Burnside Hall\, CA\, QC\, Montreal\, H3A 0B9\, 805 rue Sherbrooke Ouest SUMMARY:Tom Kaiser (Université de Neuchâtel) URL:/mathstat/channels/event/tom-kaiser-universite-de- neuchatel-287066 END:VEVENT END:VCALENDAR
