The variety $F$ is known to be a smooth projective hyperkaehler fourfold, which is moreover endowed with a self rational map $\\phi : F -\\rightarrow F$ first constructed by C. Voisin. Here we define a filtration of Bloch--Beilinson type on the Chow group of zero-cycles $CH_0(F)$ which canonically splits under the action of $\\phi$, thereby answering in this case a question of A. Beauville. Moreover, we show that this filtration is of motivic origin, in the sense that it arises from a Chow--Kuenneth decomposition of the diagonal.", "revisions": [ { "version": "v1", "updated": "2012-12-03T21:01:17.000Z", "comment": "28 pages", "journal": null, "doi": null }, { "version": "v2", "updated": "2020-10-07T08:28:29.000Z" } ], "analyses": { "subjects": [ "14C25", "14C15", "53C26", "14J28" ], "keywords": [ "chow group", "smooth complex cubic fourfold", "self rational map", "smooth projective hyperkaehler fourfold", "filtration" ], "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1212.0552S" } } }
