ON THE GROUP OF SEPARABLE QUADRATIC ALGEBRAS AND STACKS
Published online by Cambridge University Press: 20 June 2018
Abstract
The aim of this paper is to study the group of isomorphism classes of torsors of finite flat group schemes of rank 2 over a commutative ring R. This, in particular, generalizes the group of quadratic algebras (free or projective), which is especially well studied. Our approach, however, yields new results even in this case.
