Voevodsky motives and motives with modulus in positive characteristic

Abstract

Let $k$ be a perfect field of characteristic $p>0$. In this paper, without assuming resolution of singularities, we prove that the triangulated category of motives with modulus with rational coefficients is equivalent to Voevodsky's triangulated category of motives with rational coefficients $\MDM^\eff(k,\Q)\simeq \DM^\eff(k,\Q).$ Equivalently, after tensoring with $\Q$, the multiplicities of the modulus become invisible in the category of motives with modulus in positive characteristic.
