WebIn mathematics, the Hasse invariant of a quadratic form Q over a field K takes values in the Brauer group Br . The name "Hasse–Witt" comes from Helmut Hasse and Ernst Witt. The quadratic form Q may be taken as a diagonal form Its invariant is then defined as the product of the classes in the Brauer group of all the quaternion algebras WebIntroduction. The Hasse invariant of a quadratic form on a vector space over a field k is an element of the Brauer group of k. It can be generalized to a homo-morphism from the Witt group of classes of quadratic forms to the graded Brauer group of classes of graded k-algebras [3], [16]. Curiously enough, in this guise it is quite analogous to ...
