Abstract:Let A be a locally compact abelian group and let µ be a probability measure on A. A probability measure λ on A is an affine k-th root of µ if there exists a continuous automorphism ρ of A such that ρ k = I (the identity transformation) and λ * ρ(λ) * ρ 2 (λ) * • • • * ρ k−1 (λ) = µ, and µ is affinely infinitely divisible if it has affine k-th roots for all orders. Clearly every infinitely divisible probability measure is affinely infinitely divisible. In this paper we prove the converse for connected abelian L… Show more
