A non-Archimedean counterpart of Johnson's theorem for discrete groups
Abstract
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 l1(G) is amenable iff G is K-amenable in our sense.
