Density preturbations in a finite scale factor singularity universe    [PDF]

Adam Balcerzak, Tomasz Denkiewicz

We discuss evolution of density perturbations in cosmological models which admit finite scale factor singularities. After solving the matter perturbations equations we find that there exists a set of the parameters which admit a finite scale factor singularity in future and instantaneously recover matter density evolution history which are indistinguishable from the standard LCDM scenario.
