Tensor products of affine and formal abelian groups

Tilman Bauer, Magnus Carlson

In this paper we study tensor products of affine abelian group schemes over a perfect field $k .$ We first prove that the tensor product $G_{1} \otimes G_{2}$ of two affine abelian grou…

The étale cohomology ring of the ring of integers of a number field

Eric Ahlqvist, Magnus Carlson

We compute the étale cohomology ring $H^{*} (Spec O_{K}, Z / n Z)$ where $O_{K}$ is the ring of integers of a number field $K .$ As an application…
