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…
