The Real graded Brauer group
Chuck Weibel -- Rutgers University
Location: Room 005
Date & time: Wednesday, 06 February 2019 at 2:00PM - 3:00PM
We introduce a version of the Brauer--Wall group for Real vector bundles of algebras (in the sense of Atiyah), and compare it to the topological analogue of the Witt group. For varieties over the reals, these invariants capture the topological parts of the Brauer--Wall and Witt groups.
