Improper currents in theories with local invariance
Nuno Barros e Sá
We present a proof that the currents arising from Noether's first theorem in a physical theory with local invariance can always be decomposed into two terms, one of them vanishing…

Covariant conservation laws, local invariance and Noether's second theorem
Nuno Barros e Sá, Miguel A. S. Pinto, Tomás Trindade
We lay down a set of requirements for a field theory to produce a covariant conservation law out of Noether's second theorem, and show that neither local invariance implies a covar…
