# 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.
