The final exam with suggested solutions is now available here.

Revision slides for the course are now posted, first part and second part.

A selection of previous exams for the course can be found here, some of them even with solutions. Since the contents of the course varies slightly each time, the following problems are probably best avoided as exam practive (they rely on techniques and material we haven't covered):

From 2020: 2a, 2b, 3a

From 2019: 2a, 3c, 4b

From 2015: 1d

The syllabus for the course is now finalised, see here. The change from the previous version is that we are not covering all of Chapter 9 and 11.

A suggested solution to the mandatory assignment is posted here.

We will drop most of Chapter 5 from the syllabus, in particular the going-up & going down-theorems along with the section on valuation rings are taken out.

From Chapter 5, the syllabus now consists of

• p. 59-61, up until the heading "Going up theorem"
• Prop. 5.12 and Prop. 5.13.

The mandatory assignment is now posted here. Submission via Canvas, with submission deadline Thursday 12 Oct, 14:30.

I mentioned in lectures the possibility of letting you bring the textbook and notes as aids for the final exam. It turns out I'm not formally allowed to change which aids you can bring at this point in the term, so no supporting material will be allowed at the exam.

There's a weekly office hour Wednesdays 14:00-15:00, meaning if you have any questions about the course, exercises or anything else, I'll be in my office in that time (room 1112 in Abel) and free to talk.

In the course schedule you'll find my lecture notes for each lecture, along with suggested exercises, both homemade and taken from Atiyah-Macdonald. I expect the homemade problems to be easier than the ones from the book, and I try to err on the side of suggesting too many rather than too few exercises. Searching online for solutions to Atiyah Macdonald should point you to a few documents that people have put together where the book's exercises are solved.

Welcome to MAT4200 - Commutative Algebra!

We will follow Atiyah & Macdonald's Introduction to Commutative Algebra, and the preliminary plan is that we do chapters 1-9 & parts of chapter 11. A plan for what we will do in each lecture can be found under "Schedule" on this page.

The book we follow is quite terse, and for more leisurely explanations of theorems and definitions it can be worth consulting Geir Ellingsrud's notes, which are freely available here.

There is one mandatory written assignment in the course, which will be posted no later than 28 Sep, and which will have a submission deadline of 12 Oct.
