Such filtrations have previously been constructed by Loday in characteristic zero and by Bhatt-Morrow-Scholze for $p$-complete negative cyclic and periodic cyclic homology in the quasisyntomic case.", "revisions": [ { "version": "v1", "updated": "2018-08-15T18:30:24.000Z" } ], "analyses": { "subjects": [ "14F30", "14L05", "13D03" ], "keywords": [ "periodic cyclic homology", "rham cohomology", "complete negative cyclic", "characteristic zero", "construct filtrations" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
