Abstract

LetG denote a locally compact group andP(G) [P c (G)] the topological semigroup of absolutely continuous [absolutely continuous and compactly supported] probability measures onG. We say thatG isP-amenable [P c -amenable] if the topological semigroupP(G)[P c (G)] is amenable. Some combinatorial properties of this class of groups are studied. The relationship between amenability andP-amenability ofG is investigated. It is shown that for a connected solvableP c -amenable groupG, G has polynomial growth if, and only if,P c (S)={f∈P c (G)‖suppf⊂S} is amenable for any open subsemigroupS ofG.
