摘要

We study cosmological solutions with scalar field in Loop Quantum Cosmology with a number of effective potentials: massless, massive scalar field, nonlinear self-interacting potential, cyclic, bicyclic potentials We discuss how quadratic term on the energy density in modified Friedmann equation prevents occurrence of singularities Qualitative analysis with phase portrait technique is presented. Such features of solutions as inflation and cyclic behavior are considered.
