It follows that $DM^{eff}_{gm}[1/p]$ could be endowed with a Chow weight structure $w_{Chow}$ whose heart is $Chow^{eff}[1/p]$ (weight structures were introduced in a preceding paper, where the existence of $w_{Chow}$ for $DM^{eff}_{gm}Q$ was also proved). As shown in previous papers, this statement immediately yields the existence of a conservative weight complex functor $DM^{eff}_{gm}[1/p]\\to K^b(Chow^{eff}[1/p])$ (which induces an isomorphism on $K_0$-groups), as well as the existence of canonical and functorial (Chow)-weight spectral sequences and weight filtrations for any cohomology theory on $DM^{eff}_{gm}[1/p]$. We also define a certain Chow t-structure for $DM_{-}^{eff}[1/p]$ and relate it with unramified cohomology. To this end we study birational motives and birational homotopy invariant sheaves with transfers.", "revisions": [ { "version": "v6", "updated": "2011-05-02T19:04:45.000Z" } ], "analyses": { "subjects": [ "32S45", "14C15", "14E15", "14F42", "14G17", "19E15", "14C25", "14F20", "18E40", "18E30", "13D15", "18G40", "19A99" ], "keywords": [ "resolution", "birational homotopy invariant sheaves", "chow weight structure", "conservative weight complex functor", "study birational motives" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1002.2651B" } } }
