General relativity histories theory II : Invariance groups

  title={General relativity histories theory II : Invariance groups},
  author={Ntina Savvidou},
In this paper we show in detail how the histories description of general relativity carries representations of both the spacetime diffeomorphisms group and the Dirac algebra of constraints. We show that the introduction of metric-dependent equivariant foliations leads to the crucial result that the canonical constraints are invariant under the action of spacetime diffeomorphisms. Furthermore, there exists a representation of the group of generalised spacetime mappings that are functionals of… CONTINUE READING
