Dynamics of Chiral Cosmology

Understand

We perform a detailed analysis for the dynamics of Chiral cosmology in a spatially flat Friedmann-Lema\^{\i}tre-Robertson-Walker universe with a mixed potential term.

• The stationary points are categorized in four families.
• Previous results in the literature are recovered while new phases in the cosmological evolution are found.
• From our analysis we find nine different cosmological solutions, the eight describe scaling solutions, where the one is that of a pressureless fluid, while only one de Sitter solution is recovered.
