w -cosmological singularities

Year: 2010

Type: article

Abstract: In this paper we characterize barotropic index singularities of homogeneous isotropic cosmological models [M. P. Da\ifmmode \mbox{\c{}}\else \c{}\fi{}browski and T. Denkiewicz, Phys. Rev. D 79, 063521 (2009).]. They are shown to appear in cosmologies for which the scale factor is analytical with a Taylor series in which the linear and quadratic terms are absent. Though the barotropic index of the perfect fluid is singular, the singularities are weak, as it happens for other models for which the density and the pressure are regular.
