Demba Barry, Adam Chapman, Ahmed Laghribi

In this paper we associate an invariant to a biquaternion algebra $B$ over a field $K$ with a subfield $F$ such that $K / F$ is a quadratic separable extension and $\operatorname{cha…

Outer automorphisms of adjoint groups of type D and non-rational adjoint groups of outer type A

Demba Barry, Jean-Pierre Tignol

For a classical group $G$ of type $D_{n}$ over a field $k$ of characteristic different from $2$ , we show the existence of a finitely generated regular extension $R$ of $k$ su…
