  PlanetMath: algebraic number theory
Algebraic number theory is the study of algebraic numbers, their properties and their applications.
The main object of study in algebraic number theory is the number field.
This is version 30 of algebraic number theory, born on 2005-03-15, modified 2006-03-07.

 Algebraic number - Wikipedia, the free encyclopedia
Most complex numbers are transcendental, because the set of algebraic numbers is countable while the set of complex numbers, and therefore the set of transcendental numbers, is not (since the union of two countable sets is countable).
Given an algebraic number, there is a monic polynomial of least degree that has the number as a root.
An algebraic number of degree 1 is a rational number.

 Algebraic number field - Wikipedia, the free encyclopedia
In mathematics, an algebraic number field (or simply number field) is a finite-dimensional (and therefore algebraic) field extension of the rational numbers Q.
The study of algebraic number fields, and these days also of infinite algebraic extensions of the rational number field, is the central topic of algebraic number theory.
This situation changed with the discovery of p-adic numbers by Hensel in 1897; and now it is standard to consider all of the various possible embeddings of a number field F into its various topological completions at once.

 The Prime Glossary: algebraic number   (Site not responding. Last check: 2007-10-20)
A real number is an algebraic number if it is a zero of a polynomial with integer coefficients; and its degree is the least of the degrees of the polynomials with it as a zero.
For example, the rational number a/b (with a, b and non-zero integers) is an algebraic number of degree one, because it is a zero of bx-a.
In fact, almost all real numbers are transcendental because the set of algebraic numbers is countable.

 MIT OpenCourseWare | Mathematics | 18.786 Topics in Algebraic Number Theory, Spring 2006 | Home
Some important properties of algebraic numbers follow from Minkowski's theorem: given a lattice in a Euclidean space, any bounded, convex, centrally symmetric region of large enough volume contains a nonzero lattice point.
This course is a first course in algebraic number theory.
Topics to be covered include number fields, class numbers, Dirichlet's units theorem, cyclotomic fields, local fields, valuations, decomposition and inertia groups, ramification, basic analytic methods, and basic class field theory.

 Mathematical Subject Classification
The MSC is broken down into over 5,000 two-, three-, and five-digit classfications, each corresponding to a discipline of mathematics (e.g., 11 = Number theory; 11B = Sequences and sets; 11B05 = Density, gaps, topology).
The current classification system, 2000 Mathematics Subject Classification (MSC2000), is a revision of the 1991 Mathematics Subject Classification, which is the classification that has been used by MR and Zbl since the beginning of 1991.
