Groups acting on CAT(0) spaces September 27, 2016 - September 30, 2016
To apply for Funding you must register by: June 27, 2016 about 8 years ago
Parent Program:
Location: SLMath: Eisenbud Auditorium, Atrium

Show List of Speakers

The theme of the workshop is algebraic, geometric and analytical aspects of groups that act by isometries on spaces of non-positive curvature known as CAT(0) spaces. The world of CAT(0) spaces includes classical spaces such as symmetric spaces and buildings, as well as more avant-garde arrivals, such as CAT(0) cube complex. The workshop will bring together researchers studying various aspects of such groups and spaces to discuss recent developments and chart new directions in the field.    Group Photo
