Einstein–Maxwell-axion theory: dyon solution with regular electric field
In the framework of the Einstein–Maxwell-axion theory we consider static spherically symmetric solutions which describe a magnetic monopole in the axionic environment.

Birefringence induced by pp-wave modes in an electromagnetically active dynamic aether
In the framework of the Einstein–Maxwell-aether theory we study the birefringence effect, which can occur in the pp-wave symmetric dynamic aether. The dynamic aether is considered to be a latently birefringent quasi-medium, which displays this hidden ...

Carroll Expansion of General Relativity
We study the small speed of light expansion of general relativity, utilizing the modern perspective on non-Lorentzian geometry. This is an expansion around the ultra-local Carroll limit, in which light cones close up. To this end, we first rewrite the

GENERALIZED SPACES OF GENERAL RELATIVITY [PDF]
1. This paper is a revision of the paper with the same title which was published a year ago. The paper deals with a space of four dimensions V4 of coordinates xi as i takes the values 1 to 4. The geometry of the space is based upon the asymmetric functions gij and the asymmetric coefficients of connection Prk and upon the Einsteinm equation2 gij,k ...

Why Einstein did not believe that General Relativity geometrizes gravity [PDF]
I argue that, contrary to folklore, Einstein never really cared for geometrizing the gravitational or (subsequently) the electromagnetic field; indeed, he thought that the very statement that General Relativity geometrizes gravity "is not saying anything

Curvature Dynamics in General Relativity
The equations of general relativity are recast in the form of a wave equation for the Weyl tensor. This allows reformulation of gravitational wave theory in terms of curvature waves, rather than metric waves.

The 3+1 formalism in teleparallel and symmetric teleparallel gravity
Teleparallel and symmetric teleparallel gravity offer platforms in which gravity can be formulated in interesting geometric approaches, respectively given by torsion and nonmetricity. In this vein, general relativity can be expressed in three dynamically

Formal statement of the special principle of relativity [PDF]
While there is a longstanding discussion about the interpretation of the extended, general principle of relativity, there seems to be a consensus that the special principle of relativity is absolutely clear and unproblematic.
