Course Description

The course will follow the textbook with some extra material on Zeta-functions and analytic aspects at the end. After an introduction on diophantine equations and reciprocity laws we start with the systematic development: Rings of integers  in Number fields, the discriminant, unique factorization, splitting of primes, the ideal class group and the unit group, the Dedekind Zeta function and the analytic class number formula, some aspects of global class field theory.


Grades: Grades will be based on homework. Homework is due Wednesdays at 2pm in my mailbox or in class but NOT in the Ma160 mailbox.

You are welcome to discuss solutions with other students and/or "learn" them from books or other sources, but you should write your own solutions with your own words.
