Dynamical analysis of cosmological models with non-Abelian gauge vector
  fields
  In this paper we study some models where non-Abelian gauge vector fields
endowed with a SU(2) group representation are the unique source of inflation
and dark energy. These models were first introduced under the name of
gaugeflation and gaugessence, respectively. Although several realizations of
these models have been discussed, not all available parameters and initial
conditions are known. In this work, we use a dynamical system approach to find
the full parameter space of the massive version of each model. In particular,
we found that the inclusion of the mass term increases the length of the
inflationary period. Additionally, the mass term implies new behaviors for the
equation of state of dark energy allowing to distinguish this from other
prototypical models of accelerated expansion. We show that an axially symmetric
gauge field can support an anisotropic accelerated expansion within the
observational bounds.
