An Extension Theorem for Quadratic forms

Results in Mathematics, 1987
Mit Hilfe eines Fortsetzungssatzes, der sich auf quadratische Formen auf Unterräumen eines n-Vektorraumes mit \(4\leq n\leq \infty\) über kommutativem Körper bezieht, werden Aussagen über quadratische Mengen mindestens dreidimensionaler projektiver Räume bewiesen.

Hyperbolic Involutions and Quadratic Extensions

Communications in Algebra, 2010
This is a variation on a theme of Bayer-Fluckiger, Shapiro, and Tignol related to hyperbolic involutions. More precisely, criteria for the hyperbolicity of involutions of quadratic extensions of simple algebras and involutions of the form σ ⊗ τ and σ ⊗ ρ, where σ is an involution of a central simple algebra A, τ is the nontrivial automorphism of a ...

Spheres of quadratic field extensions

Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg, 1994
Sei \(L\) eine nichtkommutative quadratische Körpererweiterung des kommutativen Körpers \(K\). Der Autor stellt dann die projektive Gerade über \(L\) als Spread \(\varphi_{L/K}\) im dreidimensionalen projektiven Raum \(P\) über \(K\) dar. Als Menge von Geraden kann \(\varphi_{L/K}\) als Punktmenge auf der Kleinschen Quadrik im fünfdimensionalen ...
