Description

In this work we study the cosmological implications of a Yang-Mills-Scalar theory in the
SO(3) and SU (2) representations in expanding Friedmann-Lemaı̂tre-Robertson-Walker uni-
verse. First, we show that not all configurations of the fields are compatible with an isotropic
space-time as it is claiming in literature and then, after choosing carefully a particular con-
figuration of the fields, we use the dynamical systems technique to study the cosmological
implications of the models, in particular we show that it is posible to describe the late time
evolution of the universe.
