Abstract

In this paper, we study the main cosmological properties of the classical Friedmann equations in the case of homogeneous and isotropic Friedmann-Robertson-Walker Universe and we also generalized the expression of the Friedmann equation in the case of Loop Quantum Cosmology (LQC). Considering the M35M_{35}-model, we found the solutions of the equations considered for two particular cases, i.e. Q=0Q=0 (i.e., the de Sitter solution) and Q>0Q>0. Moreover, we considered and studied two exact cosmological solutions of the M35M_{35}-model, in particular the power-law and the exponential ones. Futhermore, we also considered a third more complicated case and we derived the solution for an arbitrary function of the time f(t)f\left(t\right). A scalar field description of the model is presented by constructing its self-interacting potential.
