Abstract
An algorithm is given to obtain generalized power asymptotic expansions of
the solutions of the Einstein equations arising for several homogeneous cos
mological models. This allows us to investigate their behavior near the ini
tial singularity or for large times. An implementation of this algorithm in
the CAS system Maple V Release 4 is described and detailed calculations fo
r three equations are shown. (C) 1998 Elsevier Science B.V.
