The Lambda CDM model or concordance model is the standard model of modern cosmology. This model contains a number of separate theories with different mathematical formulations. The subject of this paper is a proposed Lagrangian which would provide a unied mathematical framework for the concordance model of cosmology. This unication is achieved by a combination of the f(R) approach, with the standard LCDM approach. It is postulated that Dark matter-energy elds depend on the Ricci curvature R, and dark energy elds weaken as the Ricci scalar (R) increases or strengthen as R decreases. The utility of this is a great simplification compared to the currently accepted formulation. One Lagrangian plus one constraint can model the same physics as the three Lagrangian's found in the standard formulations. The unexpected degree of diculties in observing the fermion like WIMPS of dark matter in Earth based observatories are also explained by this theory.
