A Course In Algebraic Number Theory
by Robert B. Ash
Publisher: University of Illinois 2003
This is a text for a basic course in algebraic number theory, written to provide reasonable coverage for a one-semester course. The text covers the general theory of factorization of ideals in Dedekind domains, detailed calculations illustrating the use of Kummer’s theorem, the factorization of prime ideals in Galois extensions, local and global fields, etc. A standard graduate course in algebra is assumed as prerequisite.

These are preliminary notes for a modern account of the theory of complex multiplication. The reader is expected to have a good knowledge of basic algebraic number theory, and basic algebraic geometry, including abelian varieties.
