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.

真正的布拉劳集团

我们介绍了Brauer-Wall组的一个版本,用于代数的实矢量束(在Atiyah的意义上),并将其与Witt组的拓扑类似物进行比较。对于实数上的变体,这些不变量捕获了Brauer-Wall和Witt组的拓扑部分。
