Abstract: (Oxford Journals)
Gauge fields together with non-linear field equations to govern them are introduced by requiring that the Lagrangian should be invariant under an extended translation in space-time, i.e. a translation in which four parameters are replaced by four arbitrary coordinate-dependent functions. A prescription is given to convert a non-invariant canonical (“pseudo”) energy-momentum tensor into an invariant one.- gauge field theory
