The fundamental groupoid scheme and applications
Hélène Esnault, Phùng Hô Hai
We define a linear structure on Grothendieck's arithmetic fundamental group of a scheme defined over a field of characteristic 0. It allows us to link the exist…

Partial connection for -torsion line bundles in characteristic
Hélène Esnault
The aim of this brief note for the volume in honor of S. S. Chern is to give a construction for -torsion line bundles in characteristic which plays a similar rôle as the s…
On Nori's Fundamental Group Scheme
Hélène Esnault, Phùng Hô Hai, Xiaotao Sun
We determine the quotient category which is the representation category of the kernel of the homomorphism from Nori's fundamental group scheme to its étale and local parts. Pierre…
Rational Singularities and Rational Points
Manuel Blickle, Hélène Esnault
If is a projective, geometrically irreducible variety defined over a finite field $\F_q$, such that it is smooth and its Chow group of 0-cycles fulfills base change, i.e. $CH_0…
