Abstract
Recently a new type of cosmological singularity has been postulated for in?nite barotropic index w in the equation of state p = w? of the cosmological ?uid, but vanishing pressure and density at the singular event. Apparently the barotropic index w would be the only physical quantity to blow up at the singularity. In this talk we would like to discuss the strength of such singularities and compare them with other types. We show that they are weak singularities.
