Singularity-Free Cylindrical Cosmological Model
نویسنده
چکیده
A cylindrically symmetric perfect fluid spacetime with no curvature singularity is shown. The equation of state for the perfect fluid is that of a stiff fluid. The metric is diagonal and non-separable in comoving coordinates for the fluid. It is proven that the spacetime is geodesically complete and globally hyperbolic. PACS 04.20.Jb, 98.80.Hw

Singularity Free Inhomogeneous Cosmological Stiff Fluid Models
We present a singularity free class of inhomogeneous cylindrical universes filled with stiff perfect fluid (ρ = p). Its matter free (ρ = 0) limit yield two distinct vacuum spacetimes which can be considered as analogues of Kasner solution for inhomogeneous singularity free spacetime.
متن کاملSingularity-free orthogonally-transitive cylindrical spacetimes
This talk will deal to a certain extent with the natural continuation of some work in progress that was introduced last year at the Spanish Relativity Meeting in Salamanca 1, 2 and that has recently been published 3. The reason for investigating geodesic completeness of Lorentzian manifolds is twofold. From the mathematical point of view, there is no analogue for the Hopf-Rinow theorem that cha...
متن کاملGravitational Effects of Quantum Fields in the Interior of a Cylindrical Black Hole
The gravitational back-reaction is calculated for the conformally invariant scalar field within a black cosmic string interior with cosmological constant. Using the perturbed metric, the gravitational effects of the quantum field are calculated. It is found that the perturbations initially weaken the singularity. This effect differs from the case of spherical symmetry (without cosmological cons...
متن کاملSingularity-free Cosmological Solutions in String Theories
Singularity-free cosmological solutions may be obtained from the string action at tree level if the dimension of the space-time is greater than 10 and if brane configurations are taken into account. The behaviour of the dilaton field in this case is also regular. Asymptotically a radiative phase is attained indicating a smooth transition to the standard cosmological model. PACS number(s): 04.20...
متن کاملA singularity – free cosmological model with a conformally coupled scalar field
We explore the possibility of describing our universe with a singularity–free, closed, spatially homogeneous and isotropic cosmological model, using only general relativity and a suitable equation of state which produces an inflationary era. A phase transition to a radiation–dominated era occurs as a consequence of boundary conditions expressing the assumption that the temperature cannot exceed...
