Bohr compactification p adic

WebThe Bohr compactification of an LCA group We now define the Bohr compactification of an LCA group G in such a way as might come from a clever observation; if G were compact, we know from the theorems of the last section that G bb ∼= G is also compact. In some sense, G bb is compact because Gb is discrete. In WebIn mathematics, a rigid analytic space is an analogue of a complex analytic space over a nonarchimedean field.Such spaces were introduced by John Tate in 1962, as an outgrowth of his work on uniformizing p-adic elliptic curves with bad reduction using the multiplicative group.In contrast to the classical theory of p-adic analytic manifolds, rigid analytic …

In mathematics, the Bohr compactification of a topological group G is a compact Hausdorff topological group H that may be canonically associated to G. Its importance lies in the reduction of the theory of uniformly almost periodic functions on G to the theory of continuous functions on H. The concept is named after Harald Bohr who pioneered the study of almost periodic functions, on the real line.
