Friday Dec 6th is the last lecture.  According to the plan I will discuss problems 1,2,4  of the exam Dec 2011.  In addition I will comment on the following four particular topics in the course:

Computing

-primary decomposition

-factorizations of Artinian rings

-in rings of fractions

-Hilbert polynomials in graded rings

The textbook "A Term of Commutative Algebra" by Altman and Kleiman has many useful comments and alternative presentations to Atiyah- MacDonalds book.  Its digital version is available for free at

There will be one compulsory assignement in the course, to be handed in Nov. 1st.  The assignement will be posted on this page by October 4th, and will consist of a problem set.  You may certainly work together, but must hand in separately.
