Abstract:

Exact singularity-free Senovilla-type solutions are obtained in five-dimensional spacetime for a fluid with or without heat flow. The energy density and the pressure of the fluid satisfy a barotropic equation of state and remain finite throughout the evolution in each case. It is possible to find exact solutions in both the cases - one with the anisotropic pressure and the other with isotropic pressure where . The latter includes, in a special case, one of the vacuum solutions obtained earlier.
