On the gauge symmetries of the spinning particle
N. Kiriushcheva, S. V. Kuzmin, D. G. C. McKeon
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 possib…
Remarks on "Note about Hamiltonian formalism of healthy extended Hořava-Lifshitz gravity" by J. Klusoň
N. Kiriushcheva, P. G. Komorowski, S. V. Kuzmin
We reassess the conclusion by Klusoň (J. High Energy Phys. 1007 (2010) 038) that the Hamiltonian formulation of the healthy extended Hořava-Lifshitz gravity does not present any pr…
Comment on "Gauge Symmetries and Dirac Conjecture" by Y.-L. Wang, Z.-P. Li, K. Wang and some other counterexamples to the Dirac conjecture
N. Kiriushcheva, P. G. Komorowski, S. V. Kuzmin
We argue that the conclusion about the invalidity of the Dirac conjecture, made in the paper by Wang, Li, and Wang (Int. J. Theor. Phys. 48 1894, 2009), was based upon a flawed ana…
Field-parametrization dependence of Dirac's method for constrained Hamiltonians with first-class constraints: failure or triumph? Non-covariant models
N. Kiriushcheva, P. G. Komorowski, S. V. Kuzmin
We argue that the field-parametrization dependence of Dirac's procedure, for Hamiltonians with first-class constraints not only preserves covariance in covariant theories, but in n…
An Analysis of the First Order Form of Gauge Theories
N. Kiriushcheva, S. V. Kuzmin, D. G. C. McKeon
The first order form of a Maxwell theory and U(1) gauge theory in which a gauge invariant mass term appears is analyzed using the Dirac procedure. The form of the gauge transformat…
Algebraic analysis of a model of two-dimensional gravity
A. M. Frolov, N. Kiriushcheva, S. V. Kuzmin
An algebraic analysis of the Hamiltonian formulation of the model two-dimensional gravity is performed. The crucial fact is an exact coincidence of the Poisson brackets algebra of…
Canonical Analysis of the First Order Form of Topologically Massive Electrodynamics
R. N. Ghalati, N. Kiriushcheva, S. V. Kuzmin +1
The first order form of a three dimensional U(1) gauge theory in which a gauge invariant mass term appears is analyzed using the Dirac procedure. The form of the gauge transformati…
A Canonical Analysis of the Einstein-Hilbert Action in First Order Form
N. Kiriushcheva, S. V. Kuzmin, D. G. C. McKeon
Using the Dirac constraint formalism, we examine the canonical structure of the Einstein-Hilbert action , treating the metric a…
Two-dimensional metric and tetrad gravities as constrained second order systems
R. N. Ghalati, N. Kiriushcheva, S. V. Kuzmin
Using the Gitman-Lyakhovich-Tyutin generalization of the Ostrogradsky method for analyzing singular systems, we consider the Hamiltonian formulation of metric and tetrad gravities…
Comments on ``The Einstein-Hilbert Lagrangian Density in a 2-dimensional Spacetime is an Exact Differential'' by R. da Rocha and W.A. Rodrigues, Jr
N. Kiriushcheva, S. V. Kuzmin
We argue that the recent result of da Rocha and Rodrigues that in two dimensional spacetime the Lagrangian of tetrad gravity is an exact differential [1], despite the claim of the…
On Hamiltonian formulation of the Einstein-Hilbert action in two dimensions
N. Kiriushcheva, S. V. Kuzmin
It is shown that the well-known triviality of the Einstein field equations in two dimensions is not a sufficient condition for the Einstein-Hilbert action to be a total divergence,…
Dirac and Lagrangian reductions in the canonical approach to the first order form of the Einstein-Hilbert action
N. Kiriushcheva, S. V. Kuzmin
It is shown that the Lagrangian reduction, in which solutions of equations of motion that do not involve time derivatives are used to eliminate variables, leads to results quite di…
Peculiarities of the Canonical Analysis of the First Order Form of the Einstein-Hilbert Action in Two Dimensions in Terms of the Metric Tensor or the Metric Density
N. Kiriushcheva, S. V. Kuzmin, D. G. C. McKeon
The peculiarities of doing a canonical analysis of the first order formulation of the Einstein-Hilbert action in terms of either the metric tensor or the metric density $h…
A Canonical Approach to the Einstein-Hilbert Action in Two Spacetime Dimensions
N. Kiriushcheva, S. V. Kuzmin, D. G. C. McKeon
The canonical structure of the Einstein-Hilbert Lagrange density is examined in two spacetime dimensions, using the metric density and…
