IMPORTANT ANNOUNCEMENTS: 1) Sections will not meet on Monday, March 28.  2) Please read chapters I-II (Pollard & Diamond text) before the first lecture. These are just a review of part of the theory of quadratic fields and their rings of integers, covered in Math 104B (Winter 2005), and will be assumed as known. A brief review of this material will be given in lecture, on Monday 28.


WHAT IS MATH 104C? This is the third undergraduate course in number theory. In this course we examine topics from algebraic number theory and focus on the following major themes: 1) Fields of algebraic numbers (a.k.a. Number Fields); 2) Rings of algebraic integers; 3) Arithmetic in rings of algebraic integers (integral bases, ideal theory, ideal-class groups etc.); 4) Applications to Diophantine equations.

  H. Pollard and H.G. Diamond, The theory of algebraic numbers (Third, revised edition); Dover Publ. 1998You are expected to read the text BEFORE each lecture.
