Week 3

Posted on 2025-01-27

  • lecture notes
    §3 was Monday and §4 was Wednesday

    There is a bit of revisionism in the notes. During the lecture on Wednesday I noticed that I got something a bit out of order. I “fixed” the issue while lecturing, but have made a different (better) fix to the lecture notes. The material on zero-divisors and integral domains is now in §3.1 (rather than in or around §4.2).

  • Problem set 2 due 2025-01-31

    Note: I expected to talk about irreducible elements in a PID but didn’t quite get there. So I’ve removed problem 2 from the assignment; it’ll probably re-appear next week.
