Cohomology of Arithmetic Groups: Duality, Stability, and Computations (21w5011)


(Purdue University)

(University of Michigan)


The Banff International Research Station will host the "Cohomology of Arithmetic Groups: Duality, Stability, and Computations" workshop in Banff from October 10 to October 15, 2021.

The cohomology of arithmetic groups is the study of the properties of ``holes'' in geometric spaces that contain information about number theory. The workshop will bring together mathematicians with expertise in number theory, topology, and geometric group theory to tackle these problems and explore recent developments.

Speakers include: Andrew Putman, Avner Ash, Bena Tshishiku, Benson Farb, Dan Yasaki, Frank Calegari Mark McConnell, Matthew Emerton, Melody Chan, Nathalie Wahl, Nathan Broaddus, Orsola Tommas, Paul Gunnells, Peter Patzt, Sander Kupers , Tony Feng

The Banff International Research Station for Mathematical Innovation and Discovery (BIRS) is a collaborative Canada-US-Mexico venture that provides an environment for creative interaction as well as the exchange of ideas, knowledge, and methods within the Mathematical Sciences, with related disciplines and with industry. The research station is located at The Banff Centre in Alberta and is supported by Canada's Natural Science and Engineering Research Council (NSERC), the U.S. National Science Foundation (NSF), Alberta's Advanced Education and Technology, and Mexico's Consejo Nacional de Ciencia y Tecnología (CONACYT).
