Pfister involutions in characteristic two
A. -H. Nokhodkar
In characteristic two, it is shown that a central simple algebra of degree equal to a power of two with anisotropic orthogonal involution is totally decomposable, if it becomes eit…
Quadratic descent of totally decomposable orthogonal involutions in characteristic two
Amir Hossein Nokhodkar
We investigate the quadratic descent of totally decomposable algebras with involution of orthogonal type in characteristic two. Both separable and inseparable extensions are includ…
On the decomposition of metabolic involutions
Amir Hossein Nokhodkar
The problem of whether a metabolic idempotent of a central simple algebra with involution is contained in an invariant quaternion subalgebra is investigated. As an application, the…
Applications of the Wall form to unipotent isometries of index two
Amir Hossein Nokhodkar
We investigate the Wall form of unipotent elements of index two in the orthogonal group and obtain a decomposition for these elements. Also, in characteristic two, the relation bet…
