Abstract Algebra

Abstract Algebra Course Menu

An introduction to the principles and concepts of modern Abstract Algebra. Topics include groups, rings, and fields, isomorphisms, and homomorphisms with applications to number theory, the theory of equations, and geometry.
Prerequisite: Methods of Proof and Linear Algebra with a grade of C or better.

Note: This course is proof based. All homework assignments, exams and the final are graded by the instructor. An official syllabus will be provided to the student on the first day of class by the instructor.
