*G*is a topological Abelian group and $$\hat G$$ is the space of continuous homomorphisms from

*G*into the circle group $${\mathbb{T}}$$ in the compact-open topology. A dense subgroup

*D*of

*G*is said to

*determine G*if the (necessarily continuous) surjective isomorphism $$\hat G \to \hat D$$ given by $$h \mapsto h\left| D \right.$$ is a homeomorphism,...
