Introduction to Abstract Algebra

Course Description and Grading Breakdown

The second term of Math 5 will be devoted to the study of rings and modules; including some advaced topics in linear algebra. The material corresponds roughly to Chapters 7 through 12 in the text for the course, Abstract Algebra by Dummit and Foote.

Topics includes: Introduction to rings and ideals; Isomorphism Theorems; Chinese Remainder Theorem;
Euclidean domains, Principal domains, Unique Factorization domains; Polynomial rings, Irreducibility criteria for polynomials. Introduction to modules; Free modules, Finitely generated modules; Classification of finitely generated modules over PIDs; Advanced Spectral theory. 

Grading: Roughly 40% Homework, 30% Midterm, and 30% Final.

Remark on grading, proof writing and office hours:
This year we decided to take a more systematic approach to the grading of proofs in the class. Now 20% of the points will be attached to good proof writing. Student are encouraged to come to one of the office hours to present a proof and figure out the best way to write it. I will keep a running log of proof writing mistakes and corrections I see (e.g. undeclared variables). Here is a suggested principle for good proof writing:
1. Set up notation.
2. Lay out the proof in steps, where each step is either obvious or directly follows from a previous step and mention which.
3. Being rigorous is not the same as being verbose! In fact being verbose can harm a proof. Do not write down irrelevant things for the sake of writing things down.
Refer to the question sheet and the posted solutions for one idea of concise but good proofs.

* You may use a computer or calculator while doing the homework, but may not refer to this as justification for your work.  For example, "by Mathematica" is not an acceptable justification for deriving one equation from another.  Also, since computers and calculators will not be allowed on the exams, it's best not to get too dependent on them.
