Relational particle models as toy models for quantum gravity and quantum cosmology
arXiv:gr-qc/0509054 · doi:10.1063/1.2399586
Abstract
It is argued that substantial portions of both Newtonian particle mechanics and general relativity can be viewed as relational (rather than absolute) theories. I furthermore use the relational particle models as toy models to investigate the problem of time in closed-universe canonical quantum general relativity. I consider thus in particular the internal time, semiclassical and records tentative resolutions of the problem of time.
