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…
Extended Harmonic Map Equations and the Chaotic Soliton Solutions
Gang Ren, Yi-Shi Duan
In this paper, the theory of harmonic maps is extended. The soliton or traveling wave solutions of Euler's equations of the extended harmonic maps are studied. In certain cases, th…
