This course gives an introduction to algebraic number theory. The main objects of study are number fields, i.e. finite extensions of the field of rational numbers. To a number field K we will attach its ring of integers. This ring is a Dedekind domain and we will see that one of its invariants is the class number, which measures "how far" the ring is away from being a unique factorization domain. We will also study finite extensions of number fields, and how the prime ideals behave in the associated extensions of the rings of integers.

Here is a rough outline of the course (subject to change):
1) Rings of integers
2) Basic properties of Dedekind domains
3) Minkowski's theory and finiteness of the class number
4) Dirichlet's Unit Theorem
5) Extensions of Dedekind domains and ramification theory
