As an application we show that this construction furnishes a counterexample for the integral Tate conjecture in any odd characteristic for some sufficiently large finite field. We study the etale cohomology of this regular model, and as a consequence we derive that these counterexamples are not torsion.", "revisions": [ { "version": "v3", "updated": "2014-02-05T09:39:58.000Z" } ], "analyses": { "keywords": [ "chow groups", "geometrically rational", "explicit regular model", "sufficiently large finite field", "integral tate conjecture" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2012arXiv1207.4703P" } } }
