The Wave Function of the Universe by the New Euclidean Path-integral Approach in Quantum Cosmology
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.Comment: 11 page
