From the Lorentz invariant to the coframe form of gravity
Milutin Blagojević, James M. Nester
It is shown that the Lorentz invariant gravity, defined by the coframe-connection-multiplier form of the Lagrangian, can be gauge-fixed to the pure coframe form. After clari…
Local symmetries and physical degrees of freedom in gravity: a Dirac Hamiltonian constraint analysis
Milutin Blagojević, James M. Nester
In the literature on gravity, the status of local Lorentz invariance and the number of physical degrees of freedom have been controversial issues. Relying on a detailed Hami…
Quasi-local energy from a Minkowski reference
Chiang-Mei Chen, Jian-Liang Liu, James M. Nester
The specification of energy for gravitating systems has been an unsettled issue since Einstein proposed his pseudotensor. It is now understood that energy-momentum is \emph{quasi-l…
Gravitational energy is well defined
Chiang-Mei Chen, Jian-Liang Liu, James M. Nester
The energy of gravitating systems has been an issue since Einstein proposed general relativity: considered to be ill defined, having no proper local density. Energy-momentum is now…
Gravitational Energy and the Gauge Theory Perspective
Chiang-Mei Chen, James M. Nester
Gravity, and the puzzle regarding its energy, can be understood from a gauge theory perspective. Gravity, i.e., dynamical spacetime geometry, can be considered as a local gauge the…
Counting Components in the Lagrange Multiplier Formulation of Teleparallel Theories
Yen Chin Ong, James M. Nester
We investigate the Lagrange multiplier formulation of teleparallel theories, including f(T) gravity, in which the connection is not set to zero a priori and compare it with the pur…
