Exactness of locally compact groups

Brodzki, Jacek, Cave, Christopher and Li, Kang (2017) Exactness of locally compact groups Advances in Mathematics, 312, pp. 209-233. (doi:10.1016/j.aim.2017.03.020).

Record type: Article


We give some new characterizations of exactness for locally compact second countable groups. In particular, we prove that a locally compact group is exact if and only if it admits a topologically amenable action on a compact Hausdorff space. This answers an open question by Anantharaman-Delaroche.
