Non-singular G2 stiff fluid cosmologies
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper we analyse Abelian diagonal orthogonally transitive spacetimes with spacelike orbits for which the matter content is a stiff perfect fluid. The Einstein equations are…
Non-singular radiation cosmological models
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper we analyse the possibility of constructing singularity-free inhomogeneous cosmological models with a pure radiation field as matter content. It is shown that the cond…
A wide family of singularity-free cosmological models
L. Fernandez-Jambrina, L. M. Gonzalez-Romero
In this paper a family of non-singular cylindrical perfect fluid cosmologies is derived. The equation of state corresponds to a stiff fluid. The family depends on two independent f…
