Shells of twisted flag varieties and the Rost invariant

arXiv:1012.2451 · doi:10.1215/00127094-3165434

Abstract

We introduce two new general methods to compute the Chow motives of twisted flag varieties and settle a 20-year-old conjecture of Markus Rost about the Rost invariant for groups of type E7.
