Comment on `Hamiltonian formulation for the theory of gravity and canonical transformations in extended phase space' by T P Shestakova
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 upon an incompleteExpand

The Hamiltonian formulation of tetrad gravity: Three-dimensional case
The Hamiltonian formulation of tetrad gravity in any dimension higher than two, using its first-order form where tetrads and spin connections are treated as independent variables, is discussed, andExpand

Diffeomorphism Invariance in the Hamiltonian formulation of General Relativity
Abstract It is shown that when the Einstein–Hilbert Lagrangian is considered without any non-covariant modifications or change of variables, its Hamiltonian formulation leads to results consistentExpand

Scattering of a Gaussian wave packet by a reflectionless potential
The specific features of scattering of the Gaussian wave packet by the simplest of all reflectionless potentials, the Sech-squared well, are considered. The results of numerical computation show thatExpand

Influence of mass polydispersity on dynamics of simple liquids and colloids.
We conduct molecular-dynamics computer simulations of a system of Lennard-Jones particles, polydisperse in both size and mass, at a fixed density and temperature. We test for and quantify systematicExpand

Influence of mass difference on dynamic properties of isotope mixtures
We present the results of molecular dynamics computer simulations of a two-component isotope mixture of Lennard–Jones particles, monodisperse in size but different in masses, at a fixed averageExpand

On canonical transformations between equivalent hamiltonian formulations of general relativity
Two Hamiltonian formulations of general relativity, due to Pirani, Schild and Skinner (Phys. Rev. 87, 452, 1952) and Dirac (Proc. Roy. Soc. A 246, 333, 1958), are considered. Both formulations,Expand

The Hamiltonian formulation of N-bein, Einstein-Cartan, gravity in any dimension: the Progress Report (Extended version of a talk given on CAIMS-2009, June 11-14, London, Canada)
The Hamiltonian formulation of N-bein, Einstein-Cartan, gravity, using its first order form in any dimension higher than two, is analyzed. This Hamiltonian formulation allows to explicitly show whereExpand

COMMENTS, REPLIES AND NOTES: Comment on 'A note on first-order formalism and odd-derivative actions' by S Deser
We argue that the obstacles to having a first-order formalism for odd-derivative actions presented in a pedagogical note by Deser (Class. Quantum Grav. 23 5773) are based on examples which are notExpand

On the gauge symmetries of the spinning particle
We reconsider the gauge symmetries of the spinning particle by a direct examination of the Lagrangian using a systematic procedure based on the Noether identities. It proves possible to find a set ofExpand
