The canonical quadratic pair on a Clifford algebra and triality
Andrew Dolphin, Anne Quéguiner-Mathieu
We define a canonical quadratic pair on the Clifford algebra of an algebra with quadratic pair over a field. This allows us to extend to the characteristic 2 case the notion of tri…

Symplectic Involutions, quadratic pairs and function fields of conics
Andrew Dolphin, Anne Quéguiner-Mathieu
In this paper we study symplectic involutions and quadratic pairs that become hyperbolic over the function field of a conic. In particular, we classify them in degree 4 and deduce…

Totally decomposable symplectic and unitary involutions
Andrew Dolphin
We study totally decomposable symplectic and unitary involutions on central simple algebras of index 2 and on split central simple algebras respectively. We show that for every fie…
