In order to do so, we introduce a moduli space of \"$h$-block\" bundles and understand its difference with the moduli space of ordinary block bundles.", "revisions": [ { "version": "v1", "updated": "2022-10-12T20:22:33.000Z" } ], "analyses": { "subjects": [ "57R80", "55R60", "57S05", "57N37", "57Q10" ], "keywords": [ "mapping class group", "cobordant manifolds", "moduli space", "ordinary block bundles", "cobordism invariant" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
