Non-radial oscillations of anisotropic neutron stars in the Cowling approximation
Daniela D. Doneva, Stoytcho S. Yazadjiev
One of the most common assumptions in the study of neutron star models and their oscillations is that the pressure is isotopic, however there are arguments that this may not be cor…
Purely electromagnetic spacetimes
B. V. Ivanov
Electrovacuum solutions devoid of usual mass sources are classified in the case of one, two and three commuting Killing vectors. Three branches of solutions exist. Electromagnetica…
Deviation equations and weak equivalence principle in spaces with affine connection
Bozhidar Z. Iliev
Some connections between the deviation equations and weak equivalence principle are investigated.
Deviation equations in spaces with torsion
Bozhidar Z. Iliev, Sawa S. Manoff
The most general form of the deviation equations in spaces with linear connection with arbitrary torsion is derived.
Centre of mass in spaces with torsion free flat linear connection
Bozhidar Z. Iliev
The concept "centre of mass" is analyzed in spaces with torsion free flat linear connection. It is shown that under sufficiently general conditions it is almost uniquely defined, t…
Equivalence principle in classical electrodynamics
Bozhidar Z. Iliev
The principle of equivalence in gravitational physics and its mathematical base are reviewed. It is demonstrated how this principle can be realized in classical electrodynamis. In…
