Abstract:
In this work we shall explore the interplay between matter and geometry in modern cosmological theories, by considering a specific model which takes into account the coupling between the Einstein tensor and the energy-momentum tensor, extending the fundamental Einstein-Hilbert action in a non-trivial manner. After deducing the field equations the physical features of the phase space structure are explored for various coupling functions, establishing specific constraints from a theoretic point of view.
