The original one is due to Souriau and another one is the singular de Rham complex defined by a simplicial differential graded algebra. We compare the first de Rham cohomology groups of the two complexes within the \\v{C}ech--de Rham spectral sequence in diffeology. In particular, a comparison map enables us to conclude that the first singular de Rham cohomology for the irrational torus $T_\\theta$ is isomorphic to the direct sum of the original one and the group of equivalence classes of flow bundles over $T_\\theta$ with connection $1$-forms.", "revisions": [ { "version": "v1", "updated": "2020-02-17T06:49:54.000Z" } ], "analyses": { "keywords": [ "rham complex", "diffeology", "simplicial differential graded algebra", "rham cohomology groups", "rham spectral sequence" ], "note": { "typesetting": "TeX", "pages": 7, "language": "en", "license": "arXiv", "status": "editable" } } }
