Abstract: |
For any twisted flag variety, Peyre and Merkurjev produced a long exact sequence relating the K-cohomology group and the torsion part of the Chow group of codimension-two cycles. In this talk I will produce a similar exact sequence for variety X, where X is a twisted form of the blow-up of the projective-2n space at 2n+1 points, and it can be viewed as a generalization of del Pezzo surface of degree 6. |
