Amenability of locally compact groups and subspaces of $L\sp \infty(G)$
If $G$ is a locally compact group, let $\mathcal {A}$ be the set of all the functions which left average to a constant, i.e. the function $f \in {L^\infty }(G)$ such that there is a constant in the ${\left \| \right \|_{{\infty ^ - }}}$ closed convex hull of ${\{ …
