Here is the problem set for today's exam with some solutions:

Exam

Solutions

Here are some notes from the recent revision lectures:

Summary of integral extensions and dimension theory

Primary decomposition for monomial ideals

On Thursday (10:15-12:00, room 720), we will have an `oracle service', where it will be possible to ask questions about the course and work on previous exam problems.

On thursday I will cover more exam problems. Here are the relevant problems so far:

2012 (1, 2)

2014 (1, 2, 3, 4, 5) 

2015 (1, 3, 4)

2016 (1,3)

2017 (1, 2, 3, 4)

EDIT: Here are some notes for the revision lectures on these problems (use at your own risk!).

Here is a complete list of the topics covered this fall. All definitions, theorems, examples, etc can be found in Ellingsrud's text (chapters 1-13).

On monday I will start reviewing material from Chapters 1, 2, 3, 4 in the lecture notes.

Relevant problems:

2012 (1, 2)

2014 (1, 2) 

2015 (1, 3, 4)

2016 (1,3)

2017 (2)

Some solutions to the mandatory assignment can be found here.

A preliminary set of notes for the part about Dimension theory can be found here.

The notes on integral extensions, Noether normalization and Hilbert's Nullstellensatz can be found here.

Here is the mandatory assignment. Deadline: October 31st.

A preliminary version of the lecture notes (and exercises) on the Modules chapter can be found here. (These will be completed next week).

Welcome to the course MAT4200 - Commutative algebra!

We will be using the following references:

• G. Ellingsrud. "Commutative algebra"
• M. Atiyah, I. MacDonald. "Introduction to Commutative algebra"
