WebJan 1, 2013 · The original theorem of deRham says that the cohomology of this differential algebra is naturally isomorphic (as a ring) to the singular cohomology with real coefficients.

A nonzero constant vector doesn't do the job. Otherwise, it could be possible that F ( x, t) = 0, which is forbidden. More precisely, say you choose a constant w, then F ( − w, 1 / 4) = 0. So that settles that. In fact, for all x, w ( x) cannot be a multiple of x. Otherwise, t ↦ F ( x, t) will go through 0 at some point by the ...
