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…
