Loop torsors and Abhyankar's lemma
Résumé
We define the notion of loop torsors under certain group schemes defined over the localization of a regular
henselian ring A at a strict normal crossing divisor D. We provide a Galois cohomological criterion for
classifying those torsors. We revisit also the related theory of loop torsors on Laurent polynomial rings.
