The étale fundamental group and -divided sheaves in characteristic
Xiaotao Sun, Lei Zhang
We investigate how the étale fundamental group controls local systems in characteristic , namely -divided sheaves. In analogy with Grothendieck-Malcev's results for discrete…
Stratified bundles and étale fundamental group (new version)
Hélène Esnault, Xiaotao Sun
This submission replaces the arXiv:1012.5381 submission with the same title, which had been withdrawn as it contained a mistake, repaired in this submission: on projective smoo…
Stratified bundles and étale fundamental group
Hélène Esnault, Xiaotao Sun
v2: A few typos corrected, a few formulations improved. On projective smooth over an algebraically closed field of characteristic , we show that irreducible stratified bun…
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…
