Let λ, μ be regular probability measures on a locally compact abelian semigroup S , λ * μ the convolution of λ and μ, λ n the n th iterated convolution of λ, δ x the point measure of x ϵ S . We study the totalvariation of λ n –δ x * λ n for n → ∞. We shall see that for a certain class of semigroups the limit of this sequence is either 0 or 2.
