It turns out that this result is quite general. The work that follows shows the M-V property to hold on compact manifolds for any differential cohomology functor J^ associated to any Z-graded cohomology functor J(, Z) which, in each degree, assigns to a point a finitely generated group. The approach is to show that the result follows from Diagram 1, the commutative diagram we take as a definition of differential cohomology, and Diagram 2, which combines the three Mayer-Vietoris sequences for J*(, Z), J*(, R) and J*(, R/Z).", "revisions": [ { "version": "v2", "updated": "2010-11-01T20:50:03.000Z" } ], "analyses": { "keywords": [ "mayer-vietoris property", "differential cohomology functor", "quite general", "complex k-theory", "z-graded cohomology functor" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1010.5269S" } } }
