Ermakov approach for empty FRW minisuperspace oscillators
H. C. Rosu
Abstract
The formal Ermakov approach for empty FRW minisuperspace cosmological models of arbitrary Hartle-Hawking factor ordering and the corresponding squeezing features are briefly discussed as a possible means of describing cosmological evolution
