| Nov 19, 2014 at 18:10 | comment | added | Simon Pepin Lehalleur | What is your definition of P(k)? Do you take pairs (X,i) with morphisms induced by morphisms of varieties? About the second question: Arapura showed in arxiv.org/abs/0801.0261 that the full subcategory of pure Nori motives (in the sense of the subcategory of NMM(k) coming from smooth projective varieties) is equivalent to the category of pure André motives; see thm 6.4.1 in loc. cit. Now the category of André motives is equivalent to the category of pure motives for the numerical equivalence iff the Lefchetz standard conjecture is true for k. Relating Nori motives to cycles is hard! | |
