2025 IHES Summer School – Discrete Subgroups of Lie Groups: Dynamics, Actions, Rigidity

The second 2025 IHES Summer School, organized by David Fisher (Rice University) Fanny Kassel (CNRS & IHES) Ralf Spatzier (University of Michigan), and Matthew Stover (Temple University) will be held for two weeks at the Institute, from July 7 to 18, 2025.

If you want to participate, please send your application before March 16, 2025.

Discrete Subgroups of Lie Groups: Dynamics, Actions, Rigidity

Recently there has been remarkable progress on several important problems broadly centered around the study of discrete subgroups of Lie groups. The primary goal of this summer school is to allow young reseachers to come together and learn about a number of these exciting developments.

Activities will be centered around lecture series by established experts known both for their strong contributions to the field and for the high quality of their mathematical exposition. We also plan to foster an environment where these young mathematicians are able to learn from each other and have opportunities to begin new collaborations that will drive the future of the subject.

The programme of the school will consist of nine mini-courses each ranging between 3 to 5 hours of lecture, and will include evening problem sessions.

The courses will be given by

• Simion Filip, University of Chicago
• Homin Lee, Northwestern University
• Sam Mellick, Jagiellonian University and Amanda Wilkens, Carnegie Mellon University
  
• Daniel Monclair, Université Paris-Saclay
• Maria Beatrice Pozzetti, Universitá di Bologna
• Roman Sauer, Karlsruher Institut für Technologie
• Barbara Schapira, IMAG, Université de Montpellier
  
• Antoine Song, California Institute of Technology
• Nattalie Tamam, Imperial College London
