We construct a map of Lie algebras $\\Psi: \\H_{2\\ast} (L M) \\to {\\o}(\\Mc)$, where $\\H_{2\\ast} (LM)$ is the even dimensional part of the equivariant homology of $LM$, the free loop space of $M$, and $\\Mc$ is the Maurer-Cartan moduli space of the graded differential Lie algebra $\\Omega^\\ast (M, \\adp)$, the differential forms with values in the associated adjoint bundle of $P$. For a 2-dimensional manifold $M$, our Lie algebra map reduces to that constructed by Goldman in \\cite{G2}. We treat different Lie algebra structures on $\\H_{2\\ast}(LM)$ depending on the choice of the linear reductive Lie group $G$ in our discussion.", "revisions": [ { "version": "v4", "updated": "2007-03-14T12:55:21.000Z" } ], "analyses": { "subjects": [ "55P35", "57R19", "58A10", "57R22", "57N65", "55N33", "55N91" ], "keywords": [ "flat connections", "string bracket", "lie algebra map reduces", "linear reductive lie group", "free loop space" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math......2108A" } } }
