WORKSHOP — Cremona groups
05 May 2025 - 09 May 2025 • CIRM (Marseille Luminy), France
Organizer:
CIRM – Centre International de Rencontres Mathématiques
Abstract:
This workshop will bring together experts in Algebraic Geometry to discuss and try to solve problems that are relevant to the classification of finite subgroups of Cremona groups up to conjugation. Priority would be given to the following four related areas: automorphisms of Fano varieties, classification of Fano varieties with prescribed symmetry groups, rationality problems for Fano varieties over algebraically non-closed fields, and K-stability of Fano varieties, with a special focus on the real Cremona groups.

RESEARCH IN RESIDENCE — Cremona groups
12 May 2025 - 23 May 2025 • CIRM (Marseille Luminy), France
Organizer:
CIRM – Centre International de Rencontres Mathématiques
Abstract:
Symmetries of the plane/space given by rational functions come with the basic mathematical structure of a group. This group, known as the plane/space Cremona group, is huge. One way to understand this group better is to classify all its finite subgroups. For the plane Cremona group, this was done Igor Dolgachev, Jeremy Blanc and Vasily Iskovskikh two decades ago, who classified finite subgroups of the plane Cremona group up to isomorphism. We intend to obtain some progress in this direction for the space Cremona group (real and complex), which is a much more difficult task.
