The equivalence of the first and the second order variational field equations is explicitly demonstrated. The Lagrange multiplier 2-forms we use turn out to be precisely the Belinfante-Rosenfeld 2-forms that are needed to symmetrize the canonical energy-momentum tensor of the Majorana spinor.pdfPhysics, multidisciplinaryVariational field equations of a Majorana neutrino coupled to Einstein's theory of general relativityJournal Article1303-6122https://doi.org/10.55730/1300-0101.2722878624800001N/ANOIR04097
