WebJun 30, 2014 · Generalized Bohr compactification and model-theoretic connected components. For a group first order definable in a structure , we continue the study of the "definable topological dynamics" of . The special case when all subsets of are definable in the given structure is simply the usual topological dynamics of the discrete group ; in … 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 ...
