| Description | The hamiltonian constraint equation is solved for a closed, homogenous, isotropic cosmological model in Ashtekar variables. With the aid of matter in form of incoherent dust a quantum time evolution is introduced. This evolution smoothes out the singularities and approximates classical time evolution in the large-scale limit. |
