Actual notes


The November 2017 version is in the usual place.

The editing has started to move forward significantly. All of your suggestions are now in process — many are done; most others are sorted by chapter and being gradually dealt with; and there are a few that I still have to think through. There remain some sections that need serious (re)writing, but at least the content is collected (in my private notes). I may post a list of them at some point, so you aren’t alarmed by the poor state of some of the sections. There are also some very few topics I may still add. (Examples: the Koszul complex and Hilbert syzygy theorem, following Michael Kemeny; universal delta functors, following Ravi Fernando; a quick introduction to Grobner bases; gluing schemes, following Hannah Larson.)

The figures are now “complete” in the sense that they may not be beautiful, but they should be considered completely drafts, with all the content they should eventually have. In particular, please feel free to complain about them (or make suggestions).

If there issues in how things display (e.g. curved arrows), please let me know — and also which pdf viewer you are using.

The index, and formatting, both remain to be properly dealt with.

And once again I’m struck by how many people deserve thanks for their numerous comments and suggestions.  Any attempted list will leave out many people.  Most at least are obvious from this wordpress site.

The June 4, 2017 version is in the usual place.

As always, I have a big list of emails, responses, etc. that I want to respond to. Please continue to send suggestions and corrections! I’m continuing to accelerate, but my responses are still not keeping up with your comments. (But please keep them coming!)

I’ve now returned to editing and posting.  The February 7, 2017 version is in the usual place.

My goal of posting current versions every month almost worked. The December 29, 2015 version is in the usual place. (But I am only posting it on January 1, 2016 — happy new year!)

As usual, there are many small changes, but nothing that should particularly make you want to download it if you have the previous version. And as always, I have a big list of emails, responses, etc. that I want to respond to, and a number I intend to respond to fairly soon.

Following my goal of posting current versions every month, the October 24, 2015 version is in the usual place.  There are many small changes, but nothing that should particularly make you want to download it.

The September 2015 version is in the usual place.  I’m posting it because our academic year is just starting, and I will be teaching Math 216 again; this year’s course website is here.

The list of intended changes and corrections has grown again, but essentially all are small.  My intent is to try to have the changes and corrections in each chapter digested as much as possible before the courses reaches there.

The one bit of potentially new content:  David Speyer pointed out that Grobner bases are something that people could and should reasonably see in a first course.  Over lunch in Utah, I thought it through with him and Kiran Kedlaya and Tom Graber.  I will likely post a draft here before thinking about whether to including it.
