Second-order linear differential equations associated to a Riccati equation of constant coefficients
H. C. Rosu, O. Cornejo, M. Reyes +1
We present several second-order linear differential equations that are associated to a particular Riccati equation with only one constant parameter in its coefficients through the…

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.…
