The discriminant Pfister form of an algebra with involution of capacity four
Karim Johannes Becher, Nicolas Grenier-Boley, Jean-Pierre Tignol
To an orthogonal or unitary involution on a central simple algebra of degree 4, or to a symplectic involution on a central simple algebra of degree 8, we associate a Pfister form t…
Transfer of quadratic forms and of quaternion algebras over quadratic field extensions
Karim Johannes Becher, Nicolas Grenier-Boley, Jean-Pierre Tignol
A theorem of Albert-Draxl states that if a tensor product of two quaternion division algebras , over a field is not a division algebra, then there exists a separable…
Involutions and stable subalgebras
Karim Johannes Becher, Nicolas Grenier-Boley, Jean-Pierre Tignol
Given a central simple algebra with involution over an arbitrary field, étale subalgebras contained in the space of symmetric elements are investigated. The method emphasizes the s…
