On the positive mass theorem in general relativity and Lorentz covariance of the Dirac wave equation in quantum mechanics
Changbiao Wang
The positive mass theorem in general relativity states that in an asymptotically flat spacetime, if the momentum--energy tensor is divergence-free and satisfies a dominant energy c…
Criterion for testing the covariance of physical laws and Gordon optical metric
Changbiao Wang
The problem of covariance of physical quantities has not been solved fundamentally in the theory of relativity, which has caused a lot of confusion in the community; a typical exam…
Minkowski tensor in electrodynamics of moving media and three rules for construction of the physical tensors in Einstein's special relativity
Changbiao Wang
Minkowski applied Einstein's principle of relativity to moving media and developed electrodynamics of moving media. Like Einstein introduced the EM field-strength tensor f…
Fantastic quasi-photon and the symmetries of Maxwell electromagnetic theory, momentum-energy conservation law, and Fermat's principle
Changbiao Wang
In this paper, I introduce two new concepts (Minkowski quasi-photon and invariance of physical definitions) to elucidate the theory developed in my previous work [Can. J. Phys. 93,…
Resolution of two fundamental issues in the dynamics of relativity and exposure of a real version of the emperor's new clothes
Changbiao Wang
In this paper, we aim to resolve two fundamental issues in the dynamics of relativity: (i) Under what condition, the time-column space integrals of a Lorentz four-tensor constitute…
Does the Poynting vector always represent electromagnetic power flow?
Changbiao Wang
Poynting vector as electromagnetic power flow has prevailed over one hundred years in the community. However in this paper, it is shown from Maxwell equations that the Poynting vec…
