Hamiltonian cosmology in bigravity and massive gravity
Vladimir O. Soloviev
In the Hamiltonian language we provide a study of flat-space cosmology in bigravity and massive gravity constructed mostly with de Rham, Gabadadze, Tolley (dRGT) potential. It is d…
Bigravity in tetrad Hamiltonian formalism and matter couplings
Vladimir O. Soloviev
The tetrad approach is used to resolve the matrix square root appearing in the dRGT potential. Constraints and their algebra are derived for the minimal case. It is shown that the…
Canonical formalism of bigravity
Vladimir O. Soloviev
We construct the Hamiltonian formalism of bigravity for the potential of a general form. We find conditions on this potential and prove that under these conditions the formalism is…
Bigravity in Kuchar's Hamiltonian formalism. 2. The special case
Vladimir O. Soloviev, Margarita V. Tchichikina
It is proved, that, in order to avoid the ghost mode in bigravity theory, it is sufficient to impose four conditions on the potential of interaction of the two metrics. First, the…
Bigravity in Kuchar's Hamiltonian formalism. 1. The general case
Vladimir O. Soloviev, Margarita V. Tchichikina
The Hamiltonian formalism of bigravity and massive gravity is studied here for the general form of the interaction potential of two metrics. In the theories equipped with two space…
Black hole entropy from Poisson brackets (demystification of some calculations)
Vladimir O. Soloviev
Recently it has been suggested by S. Carlip that black hole entropy can be derived from a central charge of the Virasoro algebra arising as a subalgebra in the surface deformations…
