Linear media in classical electrodynamics and the Post constraint
Friedrich W. Hehl, Yuri N. Obukhov
The Maxwell equations are formulated in a generally covariant and metric-free way in 1+3 and subsequently in 4 dimensions. For this purpose, we use the excitations , $\cal…
On possible skewon effects on light propagation
Yuri N. Obukhov, Friedrich W. Hehl
We start from a local and linear spacetime relation between the electromagnetic excitation and the field strength. Then we study the generally covariant Fresnel surfaces for light…
Goedel type solution in teleparallel gravity
Yu. N. Obukhov, T. Vargas
The stationary cosmological model without closed timelike curves of Gödel type is obtained for the ideal dust matter source within the framework of the teleparallel gravity. For a…
Lessons of spin and torsion: Reply to ``Consistent coupling to Dirac fields in teleparallelism"
Yu. N. Obukhov, J. G. Pereira
In reply to the criticism made by Mielke in the pereceding Comment [Phys. Rev. D69 (2004) 128501] on our recent paper, we once again explicitly demonstrate the inconsistency of the…
To consider the electromagnetic field as fundamental, and the metric only as a subsidiary field
Friedrich W. Hehl, Yuri N. Obukhov
In accordance with an old suggestion of Asher Peres (1962), we consider the electromagnetic field as fundamental and the metric as a subsidiary field. In following up this thought,…
Electric/magnetic reciprocity in premetric electrodynamics with and without magnetic charge, and the complex electromagnetic field
Friedrich W. Hehl, Yuri N. Obukhov
We extend an axiomatic approach to classical electrodynamics, which we developed recently, to the case of non-vanishing magnetic charge. Then two axioms, namely those of the existe…
