CATALOG DESCRIPTION:

Math 01.524 Abstract Algebra I                                                                                                                 3 S.H.

Topics will include the construction of number systems, theory of groups, rings, integral domains and fields. Other than on recommendation of the advisor, this course should not be chosen if a corresponding similar course has been part of the student's undergraduate study.
 

OBJECTIVES:

Secondary school algebra is today marked by much greater attention to mathematical structure and proof. Instructional competence in algebra may thus be seriously handicapped by a lack of formal background in the content and concepts of modern algebra. It is the purpose of this course to provide opportunity to acquire this background. The course is, however, in general inappropriate for recent graduates.
