  A series of lecture notes on the elementary theory of algebraic numbers,
using only knowledge of a first-semester graduate course in algebra (primarily
groups and rings). No prerequisite knowledge of fields is required. Based
primarily on the texts of E. Hecke, Lectures on the Theory of Algebraic
Numbers, Springer-Verlag, 1981 (English translation by G. Brauer and J.
Goldman) and D. Marcus, Number Fields, Springer, 1977.
