Synopsis of course content
This course is an introduction to modern algebraic number theory. We will
cover the basics of number fields and rings of integers, Dedekind domains,
valuations and completions. We will then discuss the decomposition of
primes in extension fields and ramification theory. We will prove the
basic theorems in the geometry of numbers, the Dirichlet unit theory and
the finiteness of the class group. There will be many examples to motivate
all of these topics and applications to the study of quadratic forms, low
degree extensions, and cyclotomic fields. If time permits we will discuss
some advanced topics such as L-functions.

Prerequisites
Math 251 or permission of instructor. Specifically the student should be familiar with group theory, commutative rings and modules over them, classification of finitely generated modules over a principal ideal domain, and field theory including extensions of fields, structure of finite fields, and Galois theory. Students who are uncertain about the prerequisites should consult the instructor.
Textbooks
The following references will be put on reserve; the first will be available in the bookstore:

  • "Algebraic Number Theory" by Fröhlich and Taylor (in the bookstore)
  • "Algebraic Number Theory" by Neukirch
  • "Number Theory" by Borevich and Shafarevich
  • "Algebraic Number Theory" by Lang
Additional Information
The course should be of interest to graduate students or undergraduates interested in algebra, algebraic geometry, differential geometry, mathematical physics, topology or another area of mathematics which interacts with number theory.
