Course Documents

Here is the syllabus for the course. Of course you should read it, but here are some administrative highlights:

Homework (see below) is due every Tuesday.

I don't do office hours, I do candy hours. These are just like office hours, but with candy. Feel free to come just for the candy (or just for the math).

The textbook for this class is "Set Theory: The Independence Phenomenon" by Peter Koellner.

Midterm: October 11
Final: December 12, 2pm

Grade Breakdown:
Homework 60%
Midterm 20%

Beyond the class specifics in the syllabus, this page provides some general guidelines for classes that we should all know, but are also worth making explicit.

Homework

Homework is due (mostly) every Tuesday in class, at the start of class. See below for the exact schedule.

Homework will cover material from the previous week and will be posted no later than a week before it's due.

This year, the math department is starting Math Night where you can go to work with other set theorists on your problem sets.
