This answers a question raised by Piazza. Under this invertibility assumption, our method yields an index formula for the Dirac operator of horn-cone and of fibered horn metrics.", "revisions": [ { "version": "v1", "updated": "2006-10-24T11:44:05.000Z" } ], "analyses": { "subjects": [ "58J20" ], "keywords": [ "index theory", "fibered cusp", "dirac operator", "spin manifold", "invertibility assumption" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
