CATALOG DESCRIPTION:

Math 01.352 Theory of Numbers                                                                                                                  3  s.h.
(Math 01.210 Linear Algebra and either Math 03.150 Discrete Mathematics or Math 03.160 Discrete Structures with a grade of C- or better in all prerequisites)

This course includes divisibility properties of the integers, theory of congruence, Diophantine Analysis, congruences of higher degree, quadratic residues and famous problems of number theory.

OBJECTIVES:
It is the objective of this course to present the students an introduction to an area of pure mathematics which has intrigued nonprofessionals as well as the greatest minds of human kind since the dawn of history. A brief history of the development of numbers and some of the influential number theorist will be presented. Some application will also be considered.
