Nonstatic Reissner-Nordström metric in the perturbative theory: Embedding in the background of the FLRW cosmology, uniqueness of solutions, the TOV equation
Pham Van Ky
This article introduces a nonstatic Reissner-Nordström metric, a metric that does not emit electromagnetic waves but can emit gravitational waves. We first use the GR theory to stu…

Testing the -theory of gravity
Nguyen Anh Ky, Pham Van Ky, Nguyen Thi Hong Van
A procedure of testing the -theory of gravity is discussed. The latter is an extension of the general theory of relativity (GR). In order this extended theory (in some varian…

Perturbative solutions of the -theory of gravity in a central gravitational field and some applications
Nguyen Anh Ky, Pham Van Ky, Nguyen Thi Hong Van
Exact solutions of an -theory (of gravity) in a static central (gravitational) field have been studied in the literature quite well, but, to find and study exact solutions…
