Time: Thu 2024-11-14 11.00 - 12.00
Location: Cramer room, Albano
Participating: Peter Patzt (University of Oklahoma)
Abstract.
The cohomology of \(\mathrm{SL}_n \mathbf{Z}\) has many connections to geometry and number theory and is largely unknown. In this talk, I will give a survey about what is known about it. In particular, I will include newly found unstable classes which come from a Hopf algebra structure. This talk is on joint work with Avner Ash and Jeremy Miller.
