#### Description

This is the less theoretical of the two upper level undergraduate abstract algebra courses. (Student's planning graduate work in mathematics should take the other course in abstract algebra, MATH 403.) The course covers the basics of groups, rings, integral domains and fields. There will be a detailed study of several groups, and a study of the properties of integers and polynomials. Emphasis is on the origin of the mathematical ideas studied and the logical structure of the subject. (This course is not open to mathematics graduate students.) The last item in the list of topics could be replaced by other topics in algebra, for example, coding theory or crystallographic groups.

#### Prerequisite:

1 course with a minimum grade of C- from (MATH240, MATH341, MATH461).
