These are the following: an explicit construction given by S.Bloch, a construction in terms of the Poincare biextension of dual intermediate Jacobians, a construction in terms of K-cohomology, and a construction in terms of determinant of cohomology of coherent sheaves. A new approach to J.Franke's Chow categories is given. An explicit formula for the Weil pairing of algebraic cycles is obtained.", "revisions": [ { "version": "v2", "updated": "2009-03-07T11:23:18.000Z" } ], "analyses": { "keywords": [ "chow groups", "dual intermediate jacobians", "frankes chow categories", "poincare biextension", "explicit construction" ], "note": { "typesetting": "TeX", "pages": 42, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2008arXiv0802.1437G" } } }
