# Young Researchers Network on the Arithmetic of the Langlands Program

**Dates: **14 - 20 July 2023**Venue:** Kopp (Eifel), roughly 80km southwest of Bonn

Organizers: Ben Heuer (Goethe University Frankfurt), Andreas Mihatsch (University of Bonn), Mingjia Zhang (University of Bonn)

Scientific Program: Tony Feng (UC Berkeley), Matteo Tamiozzo (University

of Warwick)

**Description:** The Young Researchers Network (YRN) is a workshop during the Hausdorff Trimester on the arithmetic of the Langlands program. It is aimed at young mathematicians (i.e. at the PhD and Postdoc level) that work in areas related to the Langlands program. Half of the Workshop will be of learning seminar style with talks given by participants. The other half provides ample time for discussion and for joint work on examples or problems. There will also be time for socialising and hiking in the Eifel. There will be two workshop topics (see below) that run in parallel.

# Scientific Program

The YRN consists of two parallel workshops on the following topics:

• Special cycles on moduli stacks of shtukas, led by Tony Feng, which will be based on recent work of himself, Zhiwei Yun and Wei Zhang (see arxiv.org/abs/2103.11514 and arxiv.org/abs/2110.07001) Click here for details to this program

• Étale cohomology of Hilbert modular varieties, led by Matteo Tamiozzo, which will be based on recent work of himself and Ana Caraiani (see arxiv.org/abs/2107.10081) Click here for details to this program

# Participation

All participants will be provided with accomodation in Kopp (free of charge). The Registration is closed.
