Séminaire de géométrie arithmétique Let k be a perfect field of characteristic p > 0. The Hodge-Witt sheaf is a sheaf with transfer on the category of smooth k-varieties. However, since it does not satisfy the cohomological A 1 -invariance, the Hodge-Witt cohomology is not representable in Voevodsky's category of motives. One way to overcome this drawback is to consider the category of motives wit
