| Résumé: |
Géométrie Arithmétique et Motivique - Torsors on the complement of a smooth divisor - |
| Description: |
Kestutis Cesnavicius
A conjecture of Nisnevich predicts that for a smooth variety XX over a field, a smooth divisor DD in XX, and a totally isotropic reductive XX-group scheme GG, every generically trivial GG-torsor on XDX setminus D trivializes Zariski locally on XX. I will discuss this conjecture and related questions about torsors under reductive groups over regular rings. |
