Bohr compactification
WebThe Bohr compactification is defined for any topological group , regardless of whether is locally compact or abelian. One use made of Pontryagin duality between compact abelian groups and discrete abelian groups is to characterize the Bohr compactification of an arbitrary abelian locally compact topological group.
