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.

My hope of a new version each month has clearly not worked out! But here is one for April, just before the month ends. As usual, a random selection of corrections and minor improvements have been dealt with, and many more remain to do.

The April version is posted at the usual place (the April 29, 2015 version).

I am going to attempt to put up a version every month, in order to ensure that I continue to spend a little time tidying things up every so often.  So the January version is now  posted at the usual place (the January 29, 2015 version, also in e-reader format).

The list of things to do has shrunk, but there is a good deal still to do.  I have had many useful detailed comments to later digest and then include from Gurbir Dhillon, Tony Feng, Lisa Sauermann, and Jesse Silliman; and Benjamin Ljundberg, Chandrasekhar Raju, and Scott Zhang.
