Workshop "Alpbach 2022"

This workshop is organized by J. Ayoub, C. Fuchs, P. Habegger, R. Pink, G. Wüstholz, and Sarah Zerbes. The workshop takes place from June 26-July 1, 2022 at the Böglerhof in Alpbach/Tyrol, Austria.

This, the 15th in a series of Workshops in Alpbach, will feature minicourses given by world class researchers and invited talks by younger researchers, covering topics in arithmetic geometry related to Galois representations and heights. The emphasis includes not only deep theoretical developments, but also applications of a more concrete/computational nature. Minicourses presenting a broad overview of these topics, delivered by top international experts, will be complemented by invited talks highlighting recent progress.
