Analytical Solutions to the Wheeler-DeWitt Equation in Rosen-Lagrangian Cosmology via the Eisenhart Lift

Narakorn Kaewkhao, Suparat Marit, Phongpichit Channuie

The Rosen Lagrangian framework promotes the cosmological constant to a scale-factor-dependent quantity, $\Lambda (a)={\Lambda }_0{a}^{\lambda }$, thereby providing a dynamical dark energy scenario for $λ\n…
