Cyclotomic Fields and Zeta Values by Professor John Coates, , available at Book Depository with free delivery worldwide. These fields are subfields of cyclotomic fields Q(e n) where e n = e 2πi/n is a primitive complex n-th root of unity. The elements of these fields are called cyclotomics. Information concerning operations for domains of cyclotomics, for example certain integral bases of fields of cyclotomics, can be found in Chapter Abelian Number Fields.

Introduction to Cyclotomic Fields is a carefully written exposition of a central area of number theory that can be used as a second course in algebraic number theory. Starting at an elementary level, the volume covers p-adic L-functions, class numbers, cyclotomic units, Fermat's Last Theorem, and Iwasawa's theory of Z(subscript p)-extensions Cited by: Kummer'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.5/5(1).

Lang. In mathematics, the nth cyclotomic polynomial, for any positive integer n, is the unique irreducible polynomial with integer coefficients that is a divisor of − and is not a divisor of − for any k. I was doing some study on the programming language GAP and I came to know from here (in the very fist line) that " $\mathbb Q(\sqrt{5})$ is a number field that is not cyclotomic but contained in the cyclotomic field $\mathbb {Q}_5 = \mathbb Q(e^{\frac{2\pi i}{5}})$".

So I think it is an example that says that in general not all subfields of a cyclotomic field are cyclotomic. Iwasawa viewed cyclotomic fields as being analogues for number fields of the constant field extensions of algebraic geometry, and wrote a great sequence of papers investigating towers of cyclotomic fields, and more generally, Galois extensions of number fields whose Galois group is isomorphic to the additive group of p-adic integers.

Cyclotomic fields have always occupied a central place in number theory, and the so called "main conjecture" on cyclotomic fields is arguably the deepest and most beautiful theorem known about them.

Book Title:Characters and Cyclotomic Fields in Finite Geometry This monograph contributes to the existence theory of difference sets, cyclic irreducible codes and similar objects. The new method of field descent for cyclotomic integers of presribed absolute value is developed. Cyclotomic fields arise naturally in the cyclotomy problem — the division of a circle into equal parts is equivalent to the construction of a primitive root in the complex plane. The structure of cyclotomic fields is "fairly simple", and they therefore provide convenient experimental material in formulating general concepts in number theory.Properties. A cyclotomic field is the splitting field of the cyclotomic polynomial. x n − 1. and therefore it is a Galois extension of the field of rational numbers. The degree of the extension [Q(ζ n):Q]is given by φ(n) where φ is Euler's phi function.A complete set of Galois conjugates is given by { (ζ n) a }, where a runs over the set of invertible residues modulo n (so that a is.: Cyclotomic Fields (Graduate Texts in Mathematics) () by Lang, S. and a great selection of similar New, Used and Collectible Books available now at great Range:$ - \$
