Dynamical Analysis of an Integrable Cubic Galileon Cosmological Model

Understand

Recently a cubic Galileon cosmological model was derived by the assumption that the field equations are invariant under the action of point transformations.

• The cubic Galileon model admits a second conservation law which means that the field equations form an integrable system.
• The analysis of the critical points for this integrable model is the main subject of this work.
• To perform the analysis, we work on dimensionless variables different from that of the Hubble normalization.
