Official Course Description
(a.k.a. Number Theory)
Studies the set of integers, focusing on divisibility, congruences, arithmetic functions, sums of squares, quadratic residues and reciprocity, and elementary results on distributions of primes.
Prerequisite: MATH 2001.
My Unofficial Course Description
Number theory is the study of the integers. The integers have two principal structures — addition and multiplication — whose interaction creates complex behaviour. We study the distribution of primes, integral solutions to polynomial equations, and similar questions. While I may dabble in applications such as cryptography, we study these questions as pure mathematics.
My Policy on Influenza
Please keep in mind that flu is potentially life-threatening to the very old, very young, and immune-compromised. Please stay home if you are feverish or have a flu and may be contagious, and I will help you catch up.
