Kummer cyclotomic number

WebKummer's work on cyclotomic fields paved the way for the development of algebraic number theory in general by Dedekind, Weber, Hensel, Hilbert, Takagi, Artin and others. However, the success of this general theory has tended to obscure special facts proved by Kummer about cyclotomic fields which lie deeper than the general theory. WebKUMMER’S LEMMA KEITH CONRAD Let pbe an odd prime and = p be a primitive pth root of unity. In the ring Z[ ], the pth power of every element is congruent to a rational integer mod …

WebKummer's proof apparently had a gap: he "reduced" to the case when a hypothetical solution (x,y,z) in a regular cyclotomic ring of integers was pairwise relatively prime, but you can't reduce to that case if the ring has class number greater than 1. … WebKummer Theory and Reciprocity Laws Peter Stevenhagen Abstract. Insert abstract here. 1. Introduction How can we find abelian extensions of a number field? For any such field K, we have the cyclotomic extension K ⊂ K(ζ m); the Galois group will be abelian and a subgroup of (Z/mZ)∗.

Webextensions (that is, Galois extensions with abelian Galois group); cyclotomic extensions are essentially the only construction that works over all elds. Other constructions of abelian extensions are Kummer extensions, Artin-Schreier-Witt extensions, and Carlitz extensions, but these all require special conditions on the base eld. 1 Figure 1.
