Query: A non-Archimedean counterpart of Johnson's theorem for discrete groups   Let $K$ be a spherically complete field with a non-Archimedean valuation. We
define a new version of $K-$amenability for discrete groups and show that the
Banach $K-$algebra $l^1(G)$ is amenable iff $G$ is $K-$amenable in our sense.
