Hamiltonian structure of the teleparallel formulation of general relativity

We apply Dirac's Hamiltonian approach to study the canonical structure of the teleparallel form of general relativity without matter fields. It is shown, without any gauge fixing, that the Hamiltonian has the generalized Dirac-ADM form, and constraints satisfy all the consistency requirements. The set of constraints involves some extra first-class constraints, which are used to find additional gauge symmetries and clarify the gauge structure of the theory.
