A direct construction of the Rost motive, by Nikita A. Karpenko

Using Rost's nilpotence theorem for endomorphisms of a motive of a projective quadric, we give a short and direct construction of the motivic decomposition of a norm quadric obtained by Rost and used in Voevodsky's proof of the Milnor conjecture.
