Pfister's Local--Global Principle and Systems of Quadratic Forms

Uriya A. First

Let $q$ be a unimodular quadratic form over a field $K$ . Pfister's famous local--global principle asserts that $q$ represents a torsion class in the Witt group of $K$ if and only i…

On the number of generators of a separable algebra over a finite field

Uriya First, Zinovy Reichstein, Santiago Salazar

Let $F$ be a field and let $E$ be an étale algebra over $F$ , that is, a finite product of finite separable field extensions $E = F_{1} \times \dots \times F_{r}$ . The classical primiti…
