Voevodsky motive

A. Suslin and V. Voevodsky have realized a triangulated category $D^b({\mathrm{ℳℳ}}_k)$ which is supposed to be the bounded derived category of the hypothetical abelian category of mixed motive?s over $k$, predicted by Grothendieck–Beilinson–Deligne. There are variants developed by Hanamura and M. Levine. There is a different “derived” approach to mixed motives, namely the $A^1$-homotopy theory of F. Morel and Voevodsky. Voevodsky used the derived category of mixed motives to solve Milnor's conjecture in algebraic K-theory.
