Consistent solution of Einstein–Cartan equations with torsion outside matter
نویسندگان
چکیده
The Einstein-Cartan equations in first-order action of torsion are considered. From Belinfante-Rosenfeld equation special consistence conditions derived for the parameters relating them to metric. Inside matter is given by spin which leads an extended Oppenhaimer-Volkov equation. Outside a second solution found besides torsion-free Schwarzschild one with completely determined metric and vice-versa. This shown be non-spherical origin its uniqueness respect demonstrated. Unusual properties discussed different coordinate systems where cosmological constant assumes role Friedman parameter Friedman-Lama\^itre-Robertson-Walker cosmoses. Parameters specified wormholes possible. Transformations presented explore map regions expanding contracting universes form static metrics. autoparallel solved exactly compared geodesic motion. Weyl tensor reveals that here Petrov-D type.

The calculation of properties of a strongly interacting many-body system, is a challenging problem. Many efforts have been devoted to calculations of the nuclear matter properties, both at zero and at finite temperature. Most of those studies have been restricted to the quasiparticle approximation. The quasiparticle approximation can be justified in the vicinity of the Fermi energy at zero temp...

The paper deals with the propagation of a finite-amplitude circularly polarized electromagnetic plane wave through a fully ionized hot collisionless plasma, composed of Q ( > 1) types of ions and of electrons, as a strict solution of the non-relativistic self-consistent Vlasov equations within the scope of some given applicability criterions. A constant magnetic field and a constant total plasm...

SUMMARY The question we are concerned with here is the following : Let G be a torsion-free group and consider the free product Ghti of G with an innnite cyclic group (generator t). Let w be an element of Ghti?G and hhwii denote the normal closure of w in G hti, then is the natural homomorphism G ! G hti hhwii injective?
