It is conjectured that Chow-Künneth projectors exist for any X . Note the cohomology classes of Pi are the Künneth components of the diagonal class in H ðX XÞ. So the conjecture is stronger than a conjecture of Grothendieck—Conjecture (C) in his standard conjectures, [Gr], [Kl]—that the Künneth components of the diagonal be classes of algebraic cycles. Further, the projectors Pi should satisfy additional properties, [Mu 2].
