We proved in [LLR2] that the order of the Brauer group Br(X) of X is a perfect square if it is finite. Our proof is based in part on a result of Gordon [Gor], which we used in [LLR1] to establish a key formula. Thomas Geisser noted that the formula in [LLR1] is incorrect, due to an omission in [Gor]. We explain in this corrigendum how to modify the work of Gordon to establish a correct formula. The corrected formula can be used to prove the result in [LLR2] without further modifications.", "revisions": [ { "version": "v1", "updated": "2018-04-30T12:38:37.000Z" } ], "analyses": { "subjects": [ "14G15", "14G20", "14J20", "11G25" ], "keywords": [ "néron models", "lie algebras", "corrigendum", "brauer group br", "finite field" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
