Global rigidity of Anosov actions by higher rank lattices
Location: MSRI: Simons Auditorium
groups of diffeomorphisms
Zimmer's cocycle rigidity
We will discuss a recent work with Aaron Brown and Federico Rodriguez Hertz on smooth classification of Anosov actions by higher rank lattices on nilmanifolds. In particular, we will explain how the existence of an Anosov diffeomorphism from the group action leads to Anosov property of generic elements in the acting group, allowing to make use of large abelian subgroups.
