A measure invariant under group endomorphisms
Published online by Cambridge University Press: 26 February 2010
Abstract
Let G be a locally compact abelian group. Then there is a finitely additive regular set function m defined on an algebra A of Borel sets in G, m(G) = 1, such that m(T-1F) = m(F) for all F ∈ A and all surjective group endomorphisms T of G onto G.
