Noether and Hilbert (metric) energy-momentum tensors are not, in general, equivalent
Mark Robert Baker, Natalia Kiriushcheva, Sergei Kuzmin
Multiple methods for deriving the energy-momentum tensor for a physical theory exist in the literature. The most common methods are to use Noether's first theorem with the 4-parame…

Curvature tensors of higher-spin gauge theories derived from general Lagrangian densities
Mark Robert Baker, Julia Bruce-Robertson
Curvature tensors of higher-spin gauge theories have been known for some time. In the past, they were postulated using a generalization of the symmetry properties of the Riemann te…
