Webwithout use of abstract class field theory. One can say the same for an abelian extension: in this case, local reciprocity (Theorem 4.1.2) and Remark 7.6.18 together imply that we have a well-defined map.Using the cyclic case, we may see that this map is surjective; by Corollary 7.2.8 (a side effect of our proof of the Second Inequality), the map is forced to … WebOn the scope of validity of the norm limitation theorem in one-dimensional abstract local class ﬁeld theory I.D.
