Class field theory is the description of extensions of a number field (or local field) K in terms of the arithmetic of K.
For extensions with abelian Galois group, the theory was the focal point of algebraic number theory from about 1850 to 1930. The nonabelian
case has many conjectures but few proofs. In this course abelian class field theory will be completely covered, requiring the introduction
of many of the tools in the armory of the modern number theorist, such as Galois cohomology, L-series, etc. Applications of historical
and modern importance will be presented en route together with several concrete examples. Check out Milne's notes to learn more.
