Abstract:
We use the tetrad formalism to calculate a matrix square root occurring in the de Rham–Gabadadze–Tolley potential. In the minimal case, we obtain the constraints and their algebra. We show that the number of gravitational degrees of freedom corresponds to the massless and massive gravity fields. The Boulware–Deser ghost is eliminated because of two second-class constraints.
Keywords:
bigravity, bimetric gravity, Hamiltonian formalism, massive gravity, theory gravity.
