Quasilocal Center-of-Mass
James M. Nester, Feng-Feng Meng, Chiang-Mei Chen
Gravitating systems have no well-defined local energy-momentum density. Various quasilocal proposals have been made, however the center-of-mass moment (COM) has generally been over…
Spinor Formulations for Gravitational Energy-Momentum
Chiang-Mei Chen, James M. Nester, Roh-Suan Tung
We first describe a class of spinor-curvature identities (SCI) which have gravitational applications. Then we sketch the topic of gravitational energy-momentum, its connection with…
Stability of the Anisotropic Brane Cosmology
Chiang-Mei Chen, W. F. Kao
The stability of the Bianchi type I anisotropic brane cosmology is analyzed in this paper. We also study the effect of the brane solution by comparing the models on the 3-brane and…
Gravitational Energy-Momentum in MAG
James M. Nester, Chiang-Mei Chen, Yu-Heui Wu
Energy-momentum (and angular momentum) for the Metric-Affine Gravity theory is considered from a Hamiltonian perspective (linked with the Noether approach). The important roles of…
A Symplectic Hamiltonian Derivation of Quasilocal Energy-Momentum for GR
Chiang-Mei Chen, James M. Nester
The various roles of boundary terms in the gravitational Lagrangian and Hamiltonian are explored. A symplectic Hamiltonian-boundary-term approach is ideally suited for a large clas…
Einstein Gravity - Supergravity Correspondence
Chiang-Mei Chen, Dmitri V. Gal'tsov, Sergei A. Sharakin
A correspondence between the three-block truncated 11D supergravity and the 8D pure Einstein gravity with two commuting Killing symmetries is discussed. The Kaluza-Klein two-forms…
