Bohr compactification
WebIn Section 3.4, we observe that ring components can be used to describe the [definable] Bohr compactification of a discrete ring. In Section 3.5, we introduce a notion of a model-theoretic component for a topological ring and use it to describe the Bohr compactification of such a ring. Besides elementary algebraic and model-theoretic tools ... WebLet G be a maximally almost periodic (MAP) Abelian group and let B be a boundedness on G in the sense of Vilenkin. We study the relations between B and the Bohr topology of G for some well known groups with boundedness (G,B). As an application, we prove that the Bohr topology of a topological group which is topologically isomorphic to the direct product of a …
