Math 504
Algebra: Rings, modules, and representations
Fall 2012

Important dates: The final is 8:30-10:30 a.m. son Wednesday, December 12. You must use a blue book for exams.

Office Hours: Wednesday 12:45---2:45 pm, and/or by appointment, or just stop by when it suits you. I am usually here and available. My office is Padelford C-436. I am happy to answer email questions too, but I do not check my email late at night.

Grader: The grader for this course is Guangbin Zhuang. His office is PDL C-8B. His ``office'' hours are Tuesday 1:20--2:20 in the Math Lounge. You can send him email at gbzhuang@uw.edu. Please ask him if you have any questions about the grading.

Textbook: "Advanced Modern Algebra" (2nd Edition) by J.J. Rotman. I have asked for a copy to be put on reserve in the math library.

I am also going to take Homework problems from Etingof's Introduction to Representation Theory.

Grades. Your grade will be based on the homework, and the final. I will assign some homework each week, perhaps eight assignments total. Your seven best homework scores will contribute 30%, and the final will contribute 70%. In each homework set only three problems will be graded; each is worth 3 points. Except in extraordinary circumstances, late homework will not be accepted. If you miss the homework deadline, that homework will be one of those which does not contribute to your best seven. I cannot overemphasize the importance of doing the homework promptly and regularly. It is the only way to learn mathematics.

  • Course notes: I periodically write up some notes for this course. They are far less comprehensive than the textbook but perhaps their brevity is a virtue. Anyway, take a look and use them if they seem helpful to you. I would be glad to hear of any errors or omissions that come to your attention, and also suggestions for improvement.
