Minisuperspace model of Machian resolution of Problem of Time. I. Isotropic case

摘要: A local resolution to the Problem of Time that is Machian and was previously demonstrated for relational mechanics models here shown work a more widely studied quantum cosmological model. I.e., closed isotropic minisuperspace GR with minimally coupled scalar field matter. This uses firstly along lines Barbour’s at classical level. Secondly, it Machianized version semiclassical approach cosmology (the given not than semiclassical). Finally, combined histories timeless records scheme Halliwell’s work. program’s goal treatment inhomogeneous perturbations about present paper’s draws both from this qualitative parallels particle mechanics, since have nontrivial notions inhomogeneity/structure (clumping) as well linear constraints.
