Resum: |
For the spin group G = Spin2n+1 with arbitrary n, a generic G-torsor E over a field, and a parabolic subgroup P ⊂ G, we consider the generic flag variety E/P and describe its Chow ring modulo torsion. This description determines the index of E/P, completing results of [3], where the index has been determined for most P. |
