Common Slots of Bilinear and Quadratic Pfister Forms

Commutative Algebra 2018-03-01 v2

Abstract

We show that over any field FF of char(F)=2\operatorname{char}(F)=2 and 2-rank nn, there exist 2n2^n bilinear nn-fold Pfister forms that have no slot in common. This answers a question of Becher's in the negative. We provide an analogous result also for quadratic Pfister forms.
