Orthogonal involutions on central simple algebras and function fields of Severi-Brauer varieties
Anne Quéguiner-Mathieu, Jean-Pierre Tignol
An orthogonal involution on a central simple algebra , after scalar extension to the function field of the Severi--Brauer variety of , is adjoint to a qu…

Outer automorphisms of classical algebraic groups
Anne Quéguiner-Mathieu, Jean-Pierre Tignol
The so-called Tits class, associated to an adjoint absolutely almost simple algebraic group, provides a cohomological obstruction for this group to admit an outer automorphism. If…

Restricting the Rost Invariant to the Center
Skip Garibaldi, Anne Quéguiner-Mathieu
For simple simply connected algebraic groups of classical type, Merkurjev, Parimala, and Tignol gave a formula for the restriction of the Rost invariant to torsors induced from the…
