Nori motives (and mixed Hodge modules) with integral coefficients
Raphaël Ruimy, Swann Tubach
We construct abelian categories of integral Nori motivic sheaves over a scheme of characteristic zero. The first step is to study the presentable derived category of Nori motives o…

Étale motives of geometric origin
Raphaël Ruimy, Swann Tubach
Over qcqs finite-dimensional schemes, we prove that étale motives of geometric origin can be characterised by a constructibility property which is purely categorical, giving a full…
