Honors Algebra II. MATH-UA.0349-001 Spring 2017


In the first class I talked about the units in R[x]. When R is a field these are the nonconstants. But otherwise it can be more complicated. In Z_4[x] we have (2x+1)(2x+1)=1 so 2x+1 is a unit. Intriguing question, what are the units in Z_4[x]?? Thanks to the student (sorry, I forgot your name, please send me an email reminding me) who pointed this out.

Calling is not encouraged. Emailing is. Especially for those "stupid" questions (which frequently are anything but) to clarify something. Replies are often very quick -- but no promises!

Each class one student will act as scribe -- taking careful notes which will be posted on this site. The easiest is when the notes are photographed and set to Prof Spencer. If you would like to volunteer to scribe near the start of term, please send Prof. Spencer an email at spencer@cims.nyu.edu. The first few dates are: Jan 23; Jan 25; Jan 30; Feb 1. Students will scribe for just one class.


Generally there will be assignments every week. They will be put online, usually on Monday, and due at recitation. (They will be posted here.) The assignment for the first week is not to be submitted. It is posted early as an optional warmup.
