Galois extensions, positive involutions and an application to unitary space-time coding

Vincent Astier, Thomas Unger

We show that under certain conditions every maximal symmetric subfield of a central division algebra with positive unitary involution will be a Galois extension of the fixe…

Positive cones and gauges on algebras with involution

Vincent Astier, Thomas Unger

We extend the classical links between valuations and orderings on fields to Tignol-Wadsworth gauges and positive cones on finite-dimensional simple algebras with involution. We als…
