On the Weil-étale topos of regular arithmetic schemes
Matthias Flach, Baptiste Morin
We define and study a Weil-étale topos for any regular, proper scheme over $\Spec(Z)$ which has some of the properties suggested by Lichtenbaum for such a topos. In particular,…
On the Weil-étale cohomology of number fields
Baptiste Morin
We give a direct description of the category of sheaves on Lichtenbaum's Weil-étale site of a number ring. Then we apply this result to define a spectral sequence relating Weil-éta…
The Weil-étale fundamental group of a number field II
Baptiste Morin
We define the fundamental group underlying to Lichtenbaum's Weil-étale cohomology for number rings. To this aim, we define the Weil-étale topos as a refinement of the Weil-étale si…
The Weil-étale fundamental group of a number field I
Baptiste Morin
Lichtenbaum has conjectured the existence of a Grothendieck topology for an arithmetic scheme such that the Euler characteristic of the cohomology groups of the constant sheaf…
