Student Topology Seminar

This is a seminar where graduate students give talks about topology. It also goes by the name ''no progress seminar'' to contrast it with the Topology Progress Seminar. We meet from 4:00-5:00 on fridays in room 380W. We normally talk about one topic for about 4 weeks and then change topics. Email me if you want to talk: jkmiller at stanford dot edu.

Upcoming Talks:

04/13/2012

Dan Litt: Stable hotomopy groups of spheres.

Sander Kupers: Kontsevich's theorem on the formality of the little N-disks operad

He will be giving a pre-pre-Talbot talk on Kontsevich's theorem on the formality of the little N-disks operad. This theorem tells us that the cohomology algebra and the cochain algebra of this operad are quasi-isomorphic. Though this sounds abstract, it has important consequences for the rational homology of embedding spaces, which will be the topic of my pre-Talbot talk (to be announced).
