I have posted a version with slight  changes of chapter 2 (ideals) in order to synchronize exercise numbers.

I am working on chapter 4 (modules) and later to day there will come another new version with changes only in chapter 4.

This week we did 2.3 and started on 2.5 in the notes. We did Zorn's lemma (2.40)and the basic existence theorems (2.43) and (2.44). Further we stared on radicals, and did 2.57 and 2.52.

On Monday I'll do the rest of the paragraph about radicals; do parts of 2.3 + a few words on UFD's, and then continue with 2.6 about local rings.

Wellcome to MAT4200!

We shall continue using the book by Atiayh and MacDonald: "Introduction to Commutative Algebra". It is however written in a rather terse style, as the y say in the introduction, so I shall try complement the text with some notes.

They will develop during the course, but the version is already on the web.

Texts on Commutative agebra abound; Here re two that can interesting to take a look at;

A Primer of Commutative Algebra by J- S- Milne. You find it on the web: https://www.jmilne.org/math/xnotes/ca.html

Their is also the "An Algebraic Inroduction to Complex Projective Geometry by Christian Peskine."
