Journal ArticleDOI
Wave Function of the Universe
TL;DR: In this article, the ground state amplitude for a three-manifold is given by a path integral over all compact positive-definite four-geometries which have the three-geometry as a boundary.
Wave Function of the Universe
TL;DR: A proposal for the wave function of the "ground state" or state of minimum excitation: the ground-state amplitude for a three-geometry is given by a path integral over all compact positive-definite four-geometries which have the three- geometries as a boundary.
Journal ArticleDOI
Slowly Rotating Relativistic Stars. I. Equations of Structure
TL;DR: In this paper, the authors present a survey of the state of the art in the field of cyber-physical learning.Part of the survey is presented in Table 1.1.
Journal ArticleDOI
Classical equations for quantum systems
Murray Gell-Mann,James B. Hartle +1 more
TL;DR: This work investigates the requirements for coarse grainings to yield decoherent sets of histories that are quasiclassical, i.e., such that the individual histories obey, with high probability, effective classical equations of motion interrupted continually by small fluctuations and occasionally by large ones.
