Assignment #2

Announcements:

1. The course web page is www.math.ucla.edu/~baker/222a . Copies of handouts are available there, as well as a free on-line copy of the text by Burris and Sankappanavar.

2. Days 2-W and 2-F will be non-lecture reading days, because of the national mathematics meetings. Some time later we'll have a couple of special problem sessions to make up the time.
   • For 2-W, read Sections 1.1-1.3 in Burris and Sankappanavar

   • For 2-F, read Section 1.4 in Burris and Sankappanavar; also read Handout I if you don't already know this material.

3. Note that 3-M is a holiday.

4. I'll have an extra office hour 1:30-2:30 on Tuesday, January 21 (3-T).
