Comment on "Modified F(R) Hořava-Lifshitz gravity: a way to accelerating FRW cosmology" by M. Chaichian, S. Nojiri, S. D. Odintsov, M. Oksanen, A. Tureanu
N. Kiriushcheva, P. G. Komorowski, S. V. Kuzmin
The partial Hamiltonian analysis of the Hořava-type action presented in the paper by M. Chaichian, S. Nojiri, S. D. Odintsov, M. Oksanen, A. Tureanu (Class. Quant. Grav. 27 (2011)…
Comment on "Arnowitt--Deser--Misner representation and Hamiltonian analysis of covariant renormalizable gravity" by M. Chaichian, M. Oksanen, A. Tureanu
N. Kiriushcheva, P. G. Komorowski, S. V. Kuzmin
The partial Hamiltonian analysis of the actions presented in the paper by M. Chaichian, M. Oksanen, A. Tureanu (Eur. Phys. J. C 71, 1657 (2011)) is incorrect; the true algebra of c…
Lagrangian symmetries of the ADM action. Do we need a solution to the "non-canonicity puzzle"?
N. Kiriushcheva, P. G. Komorowski, S. V. Kuzmin
We argue that there is nothing puzzling in the fact that the Hamiltonian formulation of a covariant theory, General Relativity, after a non-covariant change of field variables is n…
Comment on `Hamiltonian formulation for the theory of gravity and canonical transformations in extended phase space' by T P Shestakova
N. Kiriushcheva, P. G. Komorowski, S. V. Kuzmin
We argue that the conclusion, `we cannot consider the Dirac approach as fundamental and undoubted', made in the paper by Shestakova (Class. Quantum Grav. 28 055009, 2011), is based…
Remarks on the "non-canonicity puzzle": Lagrangian symmetries of the Einstein-Hilbert action
N. Kiriushcheva, P. G. Komorowski, S. V. Kuzmin
Given the non-canonical relationship between variables used in the Hamiltonian formulations of the Einstein-Hilbert action (due to Pirani, Schild, Skinner (PSS) and Dirac) and the…
The Carter Constant for Inclined Orbits About a Massive Kerr Black Hole: near-circular, near-polar orbits
P. G. Komorowski, S. R. Valluri, M. Houde
In an extreme mass-ratio binary black hole system, a non-equatorial orbit will list (i.e. increase its angle of inclination, ι) as it evolves in Kerr spacetime. The abutment, a set…
