Billiard Representation for Multidimensional Quantum Cosmology near the Singularity
arXiv:gr-qc/9411012 · doi:10.1007/3-540-60024-8_87
Abstract
The degenerate Lagrangian system describing a lot of cosmological models is considered. When certain restrictions on the parameters of the model are imposed, the dynamics of the model near the "singularity" is reduced to a billiard on the Lobachevsky space. The Wheeler-DeWitt equation in the asymptotical regime is solved and a third-quantized model is suggested.
