  A late time asymptotic perturbative analysis of curvature coupled complex
scalar field models with accelerated cosmological expansion is carried out on
the level of formal power series expansions. For this, algebraic analogues of
the Einstein scalar field equations in Gaussian coordinates for space-time
dimensions greater than two are postulated and formal solutions are constructed
inductively and shown to be unique. The results obtained this way are found to
be consistent with already known facts on the asymptotics of such models. In
addition, the algebraic expansions are used to provide a prospect of the large
time behaviour that might be expected of the considered models.
