The graded Brauer group of Real vector bundles

We introduce a version of the Brauer–Wall group for Real vector bundles of algebras (in the sense of Atiyah), and com- pare 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.
