NEW NONDIAGONAL SINGULARITY-FREE COSMOLOGICAL PERFECT-FLUID SOLUTION

We present a new nondiagonal G2 inhomogeneous perfect-fluid solution with a barotropic equation of state p=ρ and a positive density everywhere. It satisfies the global hyperbolicity condition and has no curvature singularity anywhere. This solution is very simple in form and has two arbitrary constants. © 1995 The American Physical Society.
