Cosmological dynamics with propagating Lorentz connection modes of spin zero
Hsin Chen, Fei-Hung Ho, James M. Nester +2
The Poincare gauge theory of gravity has a Lorentz connection with both torsion and curvature. For this theory two good propagating connection modes, carrying spin- and spin-$…
Pseudotensors and quasilocal energy-momentum
C. C. Chang, J. M. Nester, C. M. Chen
Early energy-momentum investigations for gravitating systems gave reference frame dependent pseudotensors; later the quasilocal idea was developed. Quasilocal energy-momentum can b…
The quadratic spinor Lagrangian is equivalent to the teleparallel theory
R. S. Tung, J. M. Nester
The quadratic spinor Lagrangian is shown to be equivalent to the teleparallel / tetrad representation of Einstein's theory. An important consequence is that the energy-momentum den…
Can Galactic Observations Be Explained by a Relativistic Gravity Theory?
Vadim V. Zhytnikov, James M. Nester
We consider the possibility of an alternative gravity theory explaining the dynamics of galactic systems without dark matter. From very general assumptions about the structure of a…
Another positivity proof and gravitational energy localizations
James M. Nester, Roh-Suan Tung
Two locally positive expressions for the gravitational Hamiltonian, one using 4-spinors the other special orthonormal frames, are reviewed. A new quadratic 3-spinor-curvature ident…
