Annotation
Exact dynamic theories induced by the subdivision of the variables in the original field theory into a background and a finite dynamic part are constructed. They exhibit a certain nonequivalence under different cases of the subidivied variables. Gauge invariance that follows from displacements in 4-space and dynamic theories in GTR are discussed.
