Strength of the singularities, equation of state and asymptotic expansion

Abstract

In this paper an explicit cosmological model which allows cosmological singularities are discussed. The generalized power-law and asymptotic expansions of the baro-tropic fluid index $\omega$ and equivalently the deceleration parameter $q$, in terms of cosmic time ${}^{\prime }{t}^{\prime }$ are considered. Finally, the strength of the found singularities is discussed.
