Phys. Rev. D 42, 482–487 (1990)Notion of time and the semiclassical regime of quantum gravityReceived 23 October 1989; published in the issue dated 15 July 1990 Using the notion of probabilistic time introduced in a previous work, we analyze the perturbed minisuperspace models of quantum gravity. For Robertson-Walker minisuperspace we show that it is possible to derive the so-called self-consistent cosmology in the semiclassical regime. The generalization to models with several semiclassical variables is also discussed. © 1990 The American Physical Society URL:
