Course info for 18.705 (Commutative Algebra) is available here.

We will be loosely following Atiyah and Macdonald, Introduction to Commutative Algebra.

My current office hours: MW 3:30-4:30pm in 2-275.

My final office hours this semester will be on Monday, December 18, at the usual time. I should have your final problem sets back from the grader by then if you want to pick them up, or you can come by at some other time for them (though I will be leaving town on Tuesday or Wednesday).

Problem sets will be posted here each Thursday (sometime between 11 am and 2 pm) and will be due the following Thursday, in lecture or via e-mail (e-mail addresses are in the course info sheet above - please send to Yu and cc me, and have the subject line be "18.705 - Problem Set N").
