Boundary term, extended Witten identities and positivity of energy
G. Y. Chee, Jingfei Zhang, Yongxin Guo
In terms of two-spinors a chiral formulation of general relativity with the Ashtekar Lagrangian and its Hamiltonian formalism in which the basic dynamic variables are the dyad spin…
Self-dual teleparallel gravity and the positive energy theorem
G. Y. Chee
A self-dual and anti-self-dual decomposition of the teleparallel gravity is carried out and the self-dual Lagrangian of the teleparallel gravity which is equivalent to the Ashtekar…
Symmetric Hyperbolic System in the Self-dual Teleparallel Gravity
G. Y. Chee, Yongxin Guo
In order to discuss the well-posed initial value formulation of the teleparallel gravity and apply it to numerical relativity a symmetric hyperbolic system in the self-dual telepar…
Gravitational energy-momentum and the Hamiltonian formulation of the teleparallel gravity
G. Y. Chee, Ye Zhang, Yongxin Guo
The transformation properties of the gravitational energy-momentum in the teleparallel gravity are analyzed. It is proved that the gravitational energy-momentum in the teleparallel…
