Series expansions and sudden singularities    [PDF]

John D. Barrow, S. Cotsakis, A. Tsokaros

We construct solutions of the Friedmann equations near a sudden singularity using generalized series expansions for the scale factor, the density, and the pressure of the fluid content. In this way, we are able to arrive at a solution with a sudden singularity containing two free constants, as required for a general solution of the cosmological equations.
