Ermakov approach for Q=0 empty FRW minisuperspace oscillators
arXiv:gr-qc/9910070
Abstract
The Wheeler-DeWitt equation for empty FRW minisuperspace universes of Hartle-Hawking factor ordering parameter Q=0 is mapped onto the dynamics of a unit mass classical oscillator. The latter is studied by the classical Ermakov invariant method. Angle quantities are presented in the same context
