<i>J</i> -INVARIANT OF LINEAR ALGEBRAIC GROUPS OF OUTER TYPE
Abstract We extend the notion of the J -invariant to arbitrary semisimple linear algebraic groups and provide complete decompositions for the normed Chow motives of all generically quasi-split twisted flag varieties. Besides, we establish some combinatorial patterns for normed Chow groups and motives and provide some explicit formulae for values of the J -invariant.
