# Schedule for Algebraic Number Theory 2007 Course

This is the plan for this course. We will not do everything in each listed chapter in class, and students will be expected to read in the book everything we skip in class. The prerequisites are fairly modest and the material is extremely interesting and useful and foundational to other mathematics.

Week 1:
* (sept 26) Introduction to algebraic number theory
* (sept 28) Finitely generated abelian groups

Week 2:
LECTURER THIS WEEK: Trevor Arnold
* (Oct 1) Noetherian rings (part 1)
* (Oct 3) The Hilbert Basis theorem (with proof)
* (Oct 5) Algebraic integers; norm and trace

Week 3:
* (Oct 8)  Dedekind domains and the ring of integers
* (Oct 10) Introduction to Sage
* (Oct 12) The group of fractional ideals in a Dedekind domain

Week 4:
* (Oct 15) Unique factorization of ideals; examples
* (Oct 17) Factoring rational primes in number fields:
special algorithm
* (Oct 19) Factoring rational primes in number fields:
general algorithm

Week 5:
* (Oct 22) No Class
* (Oct 24) The generalized Chinese remainder theorem
* (Oct 26) GUEST LECTURER (Koopa Koo) -- Cyclotomic fields

Week 6:
* (Oct 29) Discriminants and ramification
* (Oct 31) Norms of ideals; start of class groups
* (Nov 2)  [receive midterm] Class groups of
number fields: definition and examples

Week 7:

Dirichlet's Unit Theorem

Week 8:
* (Nov 12) No class.
* (Nov 14) LECTURER (T Arnold) -- Proof of Dirichlet's
Unit Theorem

extensions: e, f, and n
