Black hole hydrodynamics
Yuri N. Obukhov
The curved geometry of a spacetime manifold arises as a solution of Einstein's gravitational field equation. We show that the metric of a spherically symmetric gravitational field…
On a possible new type of a T odd skewon field linked to electromagnetism
Friedrich W. Hehl, Yuri N. Obukhov, Guillermo F. Rubilar
In the framework of generally covariant (pre-metric) electrodynamics (``charge & flux electrodynamics''), the Maxwell equations can be formulated in terms of the electromagnetic ex…
On the energy-momentum current of the electromagnetic field in a pre-metric axiomatic approach. I
Friedrich W. Hehl, Yuri N. Obukhov
We complete a metric-free axiomatic framework for electrodynamics by introducing the appropriate energy-momentum current Sigma of the electromagnetic field. We start from the Loren…
On physical foundations and observational effects of cosmic rotation
Yuri N. Obukhov
An overview of the cosmological models with expansion, shear and rotation is presented. Problems of the rotating models are discussed, their general kinematic properties and dynami…
A gentle introduction to the foundations of classical electrodynamics: The meaning of the excitations (D,H) and the field strengths (E, B)
Friedrich W. Hehl, Yuri N. Obukhov
The axiomatic structure of the electromagnetic theory is outlined. We will base classical electrodynamics on (1) electric charge conservation, (2) the Lorentz force, (3) magnetic f…
On the gravitational moments of a Dirac particle
Yuri N. Obukhov
We consider the classical theory of the Dirac massive particle in the Riemann-Cartan spacetime. We demonstrate that the translational and the Lorentz gravitational moments, obtaine…
