Neza Zager Korenjak, 12th floor: Strip deformations and proper affine actions
Wednesday, March 13, 2019, 02:00pm - 03:00pm
The Margulis invariant gives an if and only if criterion fordeciding if a proper affine deformation of a hyperbolic surface'sfundamental group acts properly on affine 3-space. We'll discussa paper of Danciger-Gu?ritaud-Kassel, constructing all such deformationsvia the surface's arc complex.
Location: 12th floor
