Hamiltonian structure of 2+1 dimensional gravity
Pietro Menotti
A summary is given of some results and perspectives of the hamiltonian ADM approach to 2+1 dimensional gravity. After recalling the classical results for closed universes in absenc…
Gravity in 2+1 dimensions
Pietro Menotti
A review is given of some classical and quantum aspects of 2+1 dimensional gravity.
Fermi-Walker coordinates in 2+1 dimensional gravity
P. Menotti, D. Seminara
It is shown that in 2+1 dimensions the Fermi-Walker gauge allows the general solution of the problem of determining the metric from the sources in terms of simple quadratures. This…
Stationary Solutions in 2+1 Dimensional Gravity and Closed Time-Like Curves
P. Menotti, D. Seminara
We apply the reduced radial gauge to give the general solution of the metric in 2+1 dimensions in term of quadratures. It allows a complete controll on the support of the source. W…
2+1 Gravity and Closed Time-Like Curves
P. Menotti, D. Seminara
In this paper we report some results obtained by applying the radial gauge to 2+1 dimensional gravity. The general features of this gauge are reviewed and it is shown how they allo…
