A wide family of singularity-free cosmological models
arXiv:gr-qc/0402119 · doi:10.1103/PhysRevD.66.024027
Abstract
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 functions under very simple conditions. A sufficient condition for geodesic completeness is provided.
