Query: Cosmic infinity: A dynamical system approach   Dynamical system techniques are extremely useful to study cosmology. It turns
out that in most of the cases, we deal with finite isolated fixed points
corresponding to a given cosmological epoch. However, it is equally important
to analyse the asymptotic behaviour of the universe. On this paper, we show how
this can be carried out for 3-forms model. In fact, we show that there are
fixed points at infinity mainly by introducing appropriate compactifications
and defining a new time variable that washes away any potential divergence of
the system. The richness of 3-form models allows us as well to identify
normally hyperbolic non-isolated fixed points.
