Web"Higher dimensional class field theory" typically means the class field theory of higher-dimensional local fields, as developed (primarily) by Kato and Parshin. "Non-abelian … 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 $X$ .

Webtheory and 3-dimensional Chern-Simons theory. The distinguishing feature of the new invariants was their multiplicativity under unions, rather than the additivity common to classical algebraic topology invariants, such as character-istic classes. The source of additivity is the Mayer-Vietoris sequence for homology.
