This is a fairly standard graduate course on algebraic number theory.

Contents

  1. Preliminaries From Commutative Algebra
  2. Rings of Integers
  3. Dedekind Domains; Factorization
  4. The Finiteness of the Class Number
  5. The Unit Theorem
  6. Cyclotomic Extensions; Fermat's Last Theorem
  7. Valuations; Local Fields
  8. Global Fields

Prerequisites

The algebra usually covered in a first-year graduate course, including Galois theory, group theory, and multilinear algebra. An undergraduate number theory course will also be helpful.
