The Wave Function of the Universe by the New Euclidean Path-integral Approach in Quantum Cosmology | | Atushi Ishikawa

7 Oct 1992 | | Journal: | Int. J. Mod. Phys. D2 (1993) 249 | | Subject: | gr-qc hep-th | | Abstract: | The wave function of the universe is evaluated by using the Euclidean path integral approach. As is well known, the real Euclidean path integral diverges because the Einstein-Hilbert action is not positive definite. In order to obtain a finite wave function, we propose a new regularization method and calculate the wave function of the Friedmann- Robertson-Walker type minisuperspace model. We then consider a homogeneous but anisotropic type minisuperspace model, which is known as the Bianch type I model. The physical meaning of the wave function by this new regularization method is also examined. | | Source: | arXiv, gr-qc/9210003 | | Services: | Forum | Review | PDF | Favorites | |
