There are two ways to generalise the Brauer group of fields to schemes. The definition of the Brauer group of a field k in terms of central simple algebras over k readily extends to schemes as the group of equivalence classes of Azumaya algebras.

Finite Subsghemes of Group Schemes
Canadian Journal of Mathematics, 1970If G is an ordinary group and H is a non-empty subset of G, then there are two elementary criteria for H to be a subgroup of G. The first and more general is that the mapping H × H → G × G → G, via 〈x, y〉 ⟼ xy–1 factor through H. The second is that H be finite and closed under multiplication.In the category of group schemes, if one writes down the ...

Group Insurance and Group Pension Schemes
Journal of the Staple Inn Actuarial Society, 1931The subject of Group Life Insurance schemes has been quite recently discussed by the Society (J.S.S. Vol. III. No. 3) and no useful purpose can be served by a repetition of remarks regarding such schemes.However, there are two points which deserve further consideration.

VAT Grouping Schemes – Standpoint
International VAT Monitor, 2015In this article, the authors describe how VAT grouping schemes are designed in EU law and in the legal systems of the Member States, and assess how the guidelines provided by the European Commission and the constraints introduced by the jurisprudence of the ECJ shape those regimes.

Group Schemes, Formal Groups, and p-Divisible Groups
1986When the editors of this volume and organizers of the conference asked me to lecture on group schemes with an eye to applications in arithmetic, they gave me—with characteristic forethought—a nearly impossible task. I was to cover group schemes in general, finite group schemes in particular, sketch an acquaintance with formal groups, and study p ...
