Exactness of locally compact groups. (English) Zbl 1387.22009
For a discrete group $$G$$, exactness is known to be equivalent to amenability at infinity, which means that $$G$$ acts amenably on some compact Hausdorff space. The paper under review generalizes this equivalence to locally compact second countable groups. Some other characterizations of exactness are also generalized.
