Rigid meromorphic cocycles for orthogonal groups study group

(Study group in Bonn, Fall 2024)

Goal

The aim is to understand the paper Rigid meromorphic cocycles for orthogonal groups by Darmon, Gehrmann and Lipnowski.

We will meet on Thursdays 10:30 in the seminar room, with the following exceptions:

the first talk will be Friday at noon + $\epsilon$
the talk on November 14th will be in the admin conference room due to a conference

Below is a tentative plan for the talks.

Topic	Speaker	Notes
1. Primer of rigid meromorphic cocycles for SL2	Håvard	notes
2. Orthogonal groups & their symmetric spaces	Pengcheng	notes
3. Special cycles	Yingkun	notes
4. Kudla-Millson divisors	Mike	notes
5. Rigid meromorphic cocycles	Hohto	notes
6. $p$ -adic Borcherds lifts	Yingkun	notes

Rough typed-up notes from the lectures can be found here.

The main reference is the original paper. Additionally, the following references might be useful:
