An Ermakov study of Q not zero EFRW minisuperspace oscillators

H. C. Rosu, P. Espinoza

A previous work on the Ermakov approach for empty FRW minisuperspace universes of Hartle-Hawking factor ordering parameter Q=0 is extended to the Q not zero cases

Ermakov approach for Q=0 empty FRW minisuperspace oscillators

H. C. Rosu, P. Espinoza, M. Reyes

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.…
