## Abstract The experimental evidence that the equation of state (EoS) of the dark energy (DE) could be evolving with time, suggests that the Λ‐term in the gravity action should rather be an effective quantity Λ~eff~(t) involving new dynamical terms X(t). Remarkably, a class of these ΛXCDM models c
