Higher dimensional class field theory
Web5 de jun. de 2024 · it is a topological ring (i.e. addition and multiplication are continuous) if you restrict the topology to the top ring of integers O, and then under the quotient map O ↠ O / m the quotient space topology agrees with the usual topology of the 1-local first residue field. And this stays true (of course) for n-local fields for any n>=2. WebSeveral attempts at a Higher Class Field Theory have already been made, with di erent generalisations of the class group to higher dimensional schemes: Katz-Lang [4] described the maximal abelian cover of a projective regular arithmetic scheme and Serre [15] gave a description of the abelian covers of schemes over F p in terms of generalised ...
