My first class of the day was ring theory with Agboola again. As expected, he raced through the basic definitions and claimed that everything was obvious. I think the material we went through today was about analogous to the first two weeks of group theory. After class, Jeff and I went over the notes for a while, and then Jon joined us, and we continued on until we were finished. For once, I’m caught up in algebra I think. I wonder how long that will last.
My other class of the day was homotopy theory. Bigelow wasn’t there, so someone else was teaching. He kept changing his mind as to when Bigelow would be back. Thanks to SUMaC, I understood what was going on. We didn’t do anything especially formal and instead just talked about what it means for two things to be homotopy equivalent, and we went over the house with two rooms problem.
Now I need to start a new TeX file for the new algebra notes.
