Scientific paper

In this work we present a study of the evolution of two models in Loop Quantum Cosmology, one corresponding to an homogeneous isotropic model with an interacting matter field and other with a positive cosmological constant. We show that an adiabatic approximation in a perturbative scheme is in general not consistent and work out a more general setting by means of effective Loop Quantum Cosmology (LQC).
