Energy-Momentum and Gauge Conservation Laws
G. Giachetta, L. Mangiarotti, G. Sardanashvily
We treat energy-momentum conservation laws as particular gauge conservation laws when generators of gauge transformations are horizontal vector fields on fibre bundles. In particul…

Stress-Energy-Momentum Tensors in Lagrangian Field Theory. Part 2. Gravitational Superpotential
G. Giachetta, G. Sardanashvily
Our investigation of differential conservation laws in Lagrangian field theory is based on the first variational formula which provides the canonical decomposition of the Lie deriv…

Dirac Equation in Gauge and Affine-Metric Gravitation Theories
G. Giachetta, G. Sardanashvily
We show that the covariant derivative of Dirac fermion fields in the presence of a general linear connection on a world manifold is universal for Einstein's, gauge and affine-metri…
