In particular, we show that the Hochschild cohomology of the chain algebra C_*\\Omega M carries a BV algebra structure isomorphic to that of the loop homology $\\mathbb{H}_*(LM)$. Furthermore, this BV algebra structure is compatible with the usual cup product and Gerstenhaber bracket on Hochschild cohomology. To produce this isomorphism, we use a derived form of Poincar\\'e duality with C_*\\Omega M-modules as local coefficient systems, and a related version of Atiyah duality for parametrized spectra connects the algebraic constructions to the Chas-Sullivan loop product.", "revisions": [ { "version": "v1", "updated": "2011-03-31T14:43:58.000Z" } ], "analyses": { "subjects": [ "55P50", "16E30", "55U30" ], "keywords": [ "loop space", "string topology", "bv algebra structure isomorphic", "hochschild cohomology", "chas-sullivan loop product" ], "tags": [ "dissertation" ], "note": { "typesetting": "TeX", "pages": 38, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1103.6198M" } } }
