Organisational Matters

Office: Carslaw 526


Timetable for Lectures: Monday 11am - 12pm and Tuesday 11am - 12pm in Room 830.

Consultation Hours: Monday 2 - 4pm, Friday 10am - 12pm, or by appointment.

Exam: Monday 26 June, 2pm - 4:10pm, AGR (Room 829).


The goal of this course is to study commutative rings and algebras and cover some of the most fundamental theorems in the development of the field: Noether normalisation, Hilbert Nullstellensatz, and the theory of localisation and local rings, among others. Throughout the course we will discuss how to interprete commutative algebra from the view point of affine algebraic geometry and category theory.


1. Two assignments worth 20% each; they will be posted here two weeks before the due date. More details will be posted soon.

Please submit copies to Michael directly either via email or in person; identical electronic copies also need to be submitted through Turnitin.

2. A written exam worth 60% to be held at the end of semester 1, covering the whole content of the course. The exam time and venue are listed above.


The material will overlap with a number of references, but two that cover many of the subjects are:

M.F. Atiyah and I.G. Macdonald, Introduction to Commutative Algebra, Addison-Wesley 1969.

Miles Reid, Undergraduate Commutative Algebra, Cambridge University Press 1995.


Exercises will be posted here regularly every week. These will not be collected and marked, but are a good way of learning the material. Many of them are are also announced in the lecture and reproduced here.


Notes for the lectures will be posted here on an irregular basis.
