Abstract

In this paper certain Chow weight structures on the "big" triangulated motivic categories DMReffDMRDM_R^{eff}\subset DM_R are defined in terms of motives of all smooth varieties over the base field. This definition allows studying basic properties of these weight structures without applying resolution of singularities; thus we don't have to assume that the coefficient ring RR contains 1/p1/p in the case where the characteristic pp of the base field is positive. Moreover, in the case where RR satisfies the latter assumption our weight structures are "compatible" with Chow weight structures defined in previous papers (in terms of Chow motives). The results of this article yield certain Chow-weight filtration (also) on pp-adic cohomology of motives and smooth varieties.
