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-…

A new way to solve Wheeler-DeWitt equation including black hole universe
Shintaro Sawayama
One of the unsolved issues in the quantum gravity comes from the Wheeler-DeWitt equation, which is second order functional derivative equation. In this paper, we introduce a new me…
