Conservation law of energy-momentum in general relativity
Yi-Shi Duan, Jing-Ye Zhang
We explain the necessity of application of semi-metric in general relativity. A detailed discussion on the energy-momentum conservation in the general relativity is presented using…
General Covariant Equations for Fields of Arbitrary Spin
Yi-Shi Duan
To obtain a generalized wave equation for a field in general covariant form, one must define covariant differentiation of a generalized wave function describing particles with arbi…
Generalized Nonsingular Solutions for the Scalar Meson Field of a Point Charge in General Relativity Theory
Yi-Shi Duan
It has been shown that in investigating the electromagnetic and meson fields of elementary particles, the effects of gravitational interaction cannot be neglected. The present note…
Generalization of regular solutions of Einstein's gravity equations and Maxwell's equations for point-like charge
Yi-Shi Duan
In the Born, Infeld, Bopp, Podolsky and Dirac theories the electron mass is finite (or zero), but gravity effects have not been considered. Shirokov and Fisher showed that in study…
Extended Theory of Harmonic Maps Connects General Relativity to Chaos and Quantum Mechanism
Gang Ren, Yi-Shi Duan
General relativity and quantum mechanism are two separate rules of modern physics explaining how nature works. Both theories are accurate, but the direct connection between two the…
The total energy-momentum of the universe in teleparallel gravity
Yu-Xiao Liu, Zhen-Hua Zhao, Jie Yang +1
We investigate the conservation law of energy-momentum in teleparallel gravity by using general Noether theorem. The energy-momentum current has also superpotential and is therefor…
Angular Momentum Conservation Law for Randall-Sundrum Models
Yu-Xiao Liu, Yi-Shi Duan, Li-Jie Zhang
In Randall-Sundrum models, by the use of general Noether theorem, the covariant angular momentum conservation law is obtained with the respect to the local Lorentz transformations.…
Energy-momentum for Randall-Sundrum models
Yu-Xiao Liu, Li-Jie Zhang, Yong-Qiang Wang +1
We investigate the conservation law of energy-momentum for Randall-Sundrum models by the general displacement transform. The energy-momentum current has a superpotential and are th…
The relations among two transversal submanifolds and global manifold
Guo-Hong Yang, Guang-Jiong Ni, Yi-Shi Duan
In Riemann geometry, the relations among two transversal submanifolds and global manifold are discussed. By replacing the normal vector of a submanifold with the tangent vector of…
Can torsion play a role in angular momentum conservation law?
Yishi Duan, Ying Jiang
In Einstein-Cartan theory, by the use of the general Noether theorem, the general covariant angular-momentum conservation law is obtained with the respect to the local Lorentz tran…
The Bifurcation of the Topological Structure in the Sunspot's Electric Topological Current with Locally Gauge-invariant Maxwell-Chern-Simons Term
Sheng Li, Yishi Duan
The topological structure of the electric topological current of the locally gauge invariant Maxwell-Chern-Simons Model and its bifurcation is studied. The electric topological cha…
