# The background field approximation in (quantum) cosmology

@article{Parentani2000TheBF, title={The background field approximation in (quantum) cosmology}, author={R. Parentani}, journal={Classical and Quantum Gravity}, year={2000}, volume={17}, pages={1527-1547} }

We analyse the Hamilton-Jacobi action of gravity and matter in the limit where gravity is treated at the background field approximation. The motivation is to clarify when the Wheeler-DeWitt equation leads to the Schrodinger equation in a background geometry. In particular, we investigate the problem of the choice of the background and that of the corrections to the Schrodinger equation associated with this choice. To this end, we first work classically. We determine when the total action, a… Expand
