Groupoids are fundamental tools, providing an elegant framework for many problems. The purpose of this summer school is to survey some of their applications in geometry, in measurable and topological dynamics, and in operator algebras. We will have minicourses by the following lecturers:

• Camille Horbez (Université Paris Saclay) : Measure equivalence rigidity among mapping class groups
• Xin Li (Glasgow University) : Topological groupoids and their invariants
• Clara Löh (Universität Regensburg) : The dynamical view on simplicial volume
• Paolo Piazza (Sapienza Università di Roma) : K-Theoretic and homological invariants of Dirac operators

In addition, the school will feature talks by the following researchers:

• Chris Bruce
• Paulo Carrillo-Rouse
• Amandine Escalier
• Vito Felice Zenobi
• Samuel Mellick 
• Marco Moraschini
• Peter Naryshkin
• Anush Tserunyan

Participants are expected to arrive on Sunday (June 22) evening, and to leave on Friday (June 27) afternoon. Since we are full registration is now closed.

All lectures will take place in the room "amphi Turing", inside "Bâtiment Sophie Germain", 8 place Aurélie Nemours, Paris. 

• Moulay Benameur
• François Le Maître
• Nicolás Matte Bon
• Denis Perrot

This meeting is funded by CNRS, RT Tétraèdre, IMJ-PRG (also via the Operator Algebra team), ANR PLAGE and Université Paris Cité.
