Mini course: Cohomological quasi-isometry invariants

speaker: Roman Sauer (Karlsruhe Institute for Technology)

abstract: I will explain Gromov’s coupling point of view of quasi-isometry. It turns out that this notion is better suited to cohomology. After discussing the QI-invariance of finiteness conditions, cohomological dimension, the focus will be on the invariance of the cohomology algebra of nilpotent groups.
