In the year of 2023/24, I am one of the two teaching assistants for the module MA3G6 Commutative Algebra. I will update some useful resources for the students on this page.

Class Notes

These are some random UNOFFICIAL notes loosely related to the support classes and the module MA3G6 in general. I will update them weekly after each class. They may contain non-examinable proofs or off-syllabus terminologies, so please use them at your own discretion.
