In particular, if Tate's conjecture holds and rational and numerical equivalence agree up to torsion, then the groups H^i_c(X_ar,Z(n)) are finitely generated, form an integral version of l-adic cohomology with compact support, and admit a formula for the special values of the zeta-function of X.", "revisions": [ { "version": "v2", "updated": "2005-03-23T22:38:54.000Z" } ], "analyses": { "keywords": [ "special values", "finite field", "arithmetic cohomology", "zeta-function", "lichtenbaums weil-etale cohomology groups" ], "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2004math......5164G" } } }
