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. WebIn higher dimensional class field theory one tries to describe the abelian fundamental group of a scheme $X$ of arithmetic interest in terms of idelic or cycle theoretic data on $X$ . More precisely, assume that $X$ is regular and connected and fix a modulus data, that is, an effective divisor $D$ on $X$ .
