TY - JOUR ID - 636065 AU - Šteigl, Roman - Hinterleitner, Franz PY - 2006 TI - Factor ordering in standard quantum cosmology JF - Classical and Quantum Gravity VL - 2006 IS - 23 SP - 3879-3893 EP - 3879-3893 PB - Institute of Physics Publishing SN - 02649381 KW - Quantum Friedmann models with scalar field KW - factor ordering of Hamiltonian constraint KW - critical energy KW - cosmological constant N2 - The Wheeler-DeWitt equation of Friedmann models with a massless scalar field is formulated with arbitrary factor ordering of the Hamiltonian constraint and a scalar product of wave functions is constructed. A critical energy of the matter field turns out to be necessary for a dynamical evolution of the wave function of the model. The introduction of a cosmological constant does not change the essential features. ER -
