An approach to duality on abelian precompact groups

An approach to duality on abelian precompact groups

We prove that every dense subgroup of a topological abelian group has the same ā€˜convergence dualā€™ as the whole group. By the ā€˜convergence dualā€™ we mean the character group endowed with the continuous convergence structure. We draw as a corollary that the continuous convergence structure on the character group of ā€¦
