HomeMath 430, Spring 2009
Thursday, April 30
I posted some suggested problems on Galois theory on the homework page. Do as many as hold your interest, or as you need to gain some comfort with Galois groups.
Tuesday, April 28
A brief list of topics for the final exam is available. The course schedule (linked at left) also covers through the end of the semester.

In addition to the notes from yesterday, a brief list of topics for Exam 2 is here.

The notes on UFDs, the Eisenstein Criterion, and face rings are now available.

A new homework is up, due next Friday. Since it's an exam week, I intend it to be very short and straightforward.
Friday, March 6
Igor Konfisakhar (mangled email address ikonfisa AT wustl,edu) has asked me to inform you that he's available for paid tutoring. Could be a good opportunity if you want to brush up over break. Please email him for details.
Wednesday, March 4
I've posted the notes on Zorn's Lemma and Maximal Ideals, along with a new homework due after spring break.
Tuesday, February 24
I've posted some notes on the conjugacy classes of elements in Sn, as well as on our construction of the sign homomorphism via directed graphs.
Saturday, February 14
I've posted a list of topics for Exam 1, in honor of St. Valentine's abiding interest in group theory.
Wednesday, February 11
Homework set #5 is now posted. In recognition that we have an exam next week, I've made this one slightly shorter and much more straightforward/computational than the previous few homework sets. Also, I'll be collecting it on Friday, instead of Wednesday. Nonetheless, I recommend that you work seriously on it this weekend, since the material will be covered on the exam.
