Fields with bounded Brauer $2$ -torsion index

Karim Johannes Becher

It is shown that, over a field of characteristic not $2$ , the dimension of an anisotropic quadratic Pfister form of trivial total signature is at most twice the dimension of some c…

A bound on the index of exponent- $4$ algebras in terms of the $u$ -invariant

Karim Johannes Becher, Fatma Kader Bingöl

For a prime number $p$ , an integer $e \geq 2$ and a field $F$ containing a primitive $p^{e}$ -th root of unity, the index of central simple $F$ -algebras of exponent $p^{e}$ is bounded in…
