DESCRIPTION:Title: Sofic approximations and property A.\n\nConsider a resid
 ually finite group\, then given a filtration we can construct the box spac
 e of this group with respect to the chosen filtration. 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
