"Covariantizing Classical Field Theories"

We show how to enlarge the covariance groups of a wide
variety of classical field theories in such a way that the resulting
“covariantized” theories are ‘essentially equivalent’ to the
originals. In particular, our technique will render many classical
field theories generally covariant, that is, the covariantized
theories will be spacetime diffeomorphism-covariant and free of
absolute objects. Our results thus generalize the well-known
parametrization technique of Dirac and Kuchaˇr. Our constructions
apply equally well to internal covariance groups, in which context
they produce natural derivations of both the Utiyama minimal coupling
and Stu ̈ckelberg tricks.
