Generalized power expansions in cosmology

An algorithm is given to obtain generalized power asymptotic expansions of the solutions of the Einstein equations arising for several homogeneous cosmological models. This allows us to investigate their behavior near the initial singularity or for large times. An implementation of this algorithm in...
