Solving the Wheeler-DeWitt of Small Universe
Shintaro Sawayama
We can solve the Wheeler-DeWitt equation of the small universe enough to metric becomes diagonal and take a Gaussian normal coordinate. Our previous works are concerning to this pa…
Quantization of enlarged Bianchi I universe
Shintaro Sawayama
We can solve the Wheeler-DeWitt equation of the enlarged Bianchi I as inhomogeneous type universe with static restriction which had been derived by previous paper. We consider the…
Quantization of the metric diagonal spacetime with Gaussian normal coordinates
Shintaro Sawayama
In the analysis of the Wheeler-DeWitt equation, we have simplified the Hamiltonian constraint of the Wheeler-DeWitt equation using the coordinate transformation. The coordinate is…
Problem of the time and static restriction in quantum gravity
Shintaro Sawayama
The problem of the time is one of the open issues in the quantum gravity. This problem is particular problem in the canonical quantum gravity. Even in the loop gravity the problem…
Quantization of static inhomogeneous spacetime
Shintaro Sawayama
In this paper we can solve a Wheeler-DeWitt equation of the some inhomogeneous spacetime models as a local solution. From the previous study of up-to-down method we derived the sta…
One Local Solution of the Wheeler-DeWitt equation
Shintaro Sawayama
We can obtain one solution of the Hamiltonian constraint equation in the local sense. The form of the state is suggested from the up-to-down method in our previous work. The up-to-…
