Square-reflexive polynomials
Karim Johannes Becher, Parul Gupta
For a field of characteristic different from and cohomological -dimension one, quadratic forms over the rational function field are studied. A characterisation in…
The discriminant Pfister form of an algebra with involution of capacity four
Karim Johannes Becher, Nicolas Grenier-Boley, Jean-Pierre Tignol
To an orthogonal or unitary involution on a central simple algebra of degree 4, or to a symplectic involution on a central simple algebra of degree 8, we associate a Pfister form t…
Nonsplit conics in the reduction of an arithmetic curve
Karim Johannes Becher, David Grimm
For an algebraic function field and a discrete valuation of with perfect residue field , we bound the number of discrete valuations on extending whose resi…
Strong linkage for function fields of surfaces
Karim Johannes Becher, Parul Gupta
Over a global field any finite number of central simple algebras of exponent dividing is split by a common cyclic field extension of degree . We show that the same property…
