Minimal Coupling and Attractors

Understand

The effects of minimally coupling a gravity to matter on a flat Robertson-Walker geometry are explored.

• Particular attention is paid to the evolution of the symplectic structure and the Liouville measure it defines.
• We show that the rescaling freedom introduced by choice of fiducial cell leads to a symmetry between dynamical trajectories, which together with the Liouville measure provides a natural volume weighting explanation for the generic existence of attractors.
