Hi! This is the top secret student topology party webpage. Please share this webpage with anyone who might be interested! Here's last term's webpage.
We meet on Tuesdays 1:30-3:30 in Fine Hall 1201.
This term, we will have two groups; the first group will be reading [Ga1] and [BG], and the second group will be reading [Ga2], [Ga3], and [Ga4]. We will also have individual talks interspersed throughout the term.
