| Sep 14, 2015 at 9:20 | comment | added | Igor Khavkine | An impatient physicist might also appreciate explicit and accessible formulas that go along with a more pedagogical introduction. Such formulas can be found, for instance, in the appendices of the following papers: hep-th/9601124, hep-th/0111246. | |
| Sep 14, 2015 at 9:18 | comment | added | Igor Khavkine | Just a complement to Robert Bryant's answer. Once you convert (using Hodge duality) your $M^i$ and $N^{ij}$ tensor to differential forms and divergence operators to exterior derivatives, you are essentially asking whether there exists a "Poincaré lemma" for the de Rham complex on $u$-dependent differential forms. The theory of the variational bicomplex, expounded in I. Anderson's notes, was created to precisely answer that question. | |
