Course Level Recommendations
ISA offers course level recommendations in an effort to facilitate the determination of course levels by credential evaluators.We advice each institution to have their own credentials evaluator make the final decision regrading course levels.

OverviewIntroduces the modern algebraic concepts of a group and a ring. These concepts occur throughout modern mathematics and this paper looks at their properties and some applications.Modern algebra is studied all over the world, perhaps not surprising in view of its international beginnings in the late 1700s work of the Swiss mathematician Leonhard Euler, the French mathematician Joseph Louis Lagrange, and the German mathematician Carl Friedrich Gauss. Their work led to the introduction in the 1800s of the unifying abstract algebraic concepts of a group and a ring, the first of these pioneered by the British algebraist Arthur Cayley, the second due to Richard Dedekind, also German. These two notions of a group (a set with a standard operation, usually called multiplication) and a ring (a set with two operations, usually called addition and multiplication) occur throughout modern mathematics in both its pure and applied branches and, even after more than 100 years since their introduction, most of today's research in modern algebra involves the study of either groups or rings (or both!)The learning aims of the paper are principally to develop the notions of a group and ring, to see how these arise in a variety of mathematical settings, and to establish their fundamental properties. Since this is a Pure Mathematics paper which will provide the basis for further study in abstract algebra, concepts will be introduced and developed rigorously. We will be doing a lot of proofs!Course StructureMain topics:
- A review of functions; equivalence relations; modular arithmetic
- Groups; subgroups; homomorphism and isomorphism; cosets and normal subgroups; quotient groups; Lagrange's theorem; group actions
- Rings; subrings; integral domains; matrix rings; polynomial rings; homomorphism and isomorphism; ideals; quotient rings; The Chinese Remainder theorem
Learning Outcomes: Demonstrate the ability to use mathematical reasoning by writing proofs in the context of groups and rings.
Courses and course hours of instruction are subject to change.
Eligibility for courses may be subject to a placement exam and/or pre-requisites.
Some courses may require additional fees.
Credits earned vary according to the policies of the students' home institutions. According to ISA policy and possible visa requirements, students must maintain full-time enrollment status, as determined by their home institutions, for the duration of the program.
Please reference fall and spring course lists as not all courses are taught during both semesters.
Availability of courses is based on enrollment numbers. All students should seek pre-approval for alternate courses in the event of last minute class cancellations
Please note that some courses with locals have recommended prerequisite courses. It is the student's responsibility to consult any recommended prerequisites prior to enrolling in their course.
