From this, we deduce the existence of H-structures on a component of the mapping space $\\map(X, Y)$, assuming the cohomology algebras of $X$ and $Y$ are isomorphism. Finally, we will show that $\\map(X, Y; f)\\simeq\\map(X, Y; f')$ if the corresponding \\emph{Maurer-Cartan elements} are connected by an algebra automorphism of $H^\\ast(X, \\Q)$.", "revisions": [ { "version": "v1", "updated": "2020-10-09T13:50:58.000Z" } ], "analyses": { "subjects": [ "55P62", "54C35" ], "keywords": [ "rational homotopy type", "cohomology algebra", "mapping space", "algebra automorphism", "two-stage space" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
