COURSE DESCRIPTION:
Number theory is (obviously) the study of numbers, particularly the study of whole numbers and rational numbers. In this course, we will study areas motivated by questions from ancient Greece, especially primes and prime factorization, congruences, Euler's function, quadratic reciprocity, primitive roots, solutions to polynomial congruences (Chevalley's theorem), Diophantine equations including the Pythagorean and Pell equations, and Dirichlet's theorem on primes.

TEXTBOOK: Number Theory by George Andrews

HOMEWORK: Homework will be assigned Thursday and due on the following Friday at my office by noon. It will be corrected, returned, and discussed/presented the following Tuesday. On some of the homeworks I will assign Challenge Problems; these are for extra credit. Late homework will not be accepted.

TESTS: There will be two midterms and a final. The midterms will be October 8 and November 12. The final will be on December 11 at 9 a.m.

GRADING: The grading scheme will be as follows:

Midterms: 20%
Final 40%
Homework and Class Participation: 20%

ACADEMIC DISHONESTY: I have zero tolerance for academic dishonesty. Cheating of any kind will be prosecuted to the fullest extent in accordance with university policy.

WORKING TOGETHER: Working together on the homework is allowed; however, each person must submit his or her own homework. Naturally, there is no collaboration on tests.
