Operator Ordering Ambiguity and Third Quantization
Yoshiaki Ohkuwa, Yasuo Ezawa, Mir Faizal
In this paper, we will constrain the operator ordering ambiguity of Wheeler-DeWitt equation by analyzing the quantum fluctuations in the universe. This will be done using a third q…
Virtual Black Holes in a Third Quantized Formalism
Yoshiaki Ohkuwa, Mir Faizal, Yasuo Ezawa
In this paper, we will analyse virtual black holes using the third quantization formalism. As the virtual black hole model depends critically on the assumption that the quantum flu…
Constraints on Operator Ordering from Third Quantization
Yoshiaki Ohkuwa, Mir Faizal, Yasuo Ezawa
In this paper, we analyse the Wheeler-DeWitt equation in the third quantized formalism. We will demonstrate that for certain operator ordering, the early stages of the universe are…
On the canonical formalism of -type gravity using Lie derivatives
Yoshiaki Ohkuwa, Yasuo Ezawa
We present a canonical formalism of the -type gravity using the Lie derivatives instead of the time derivatives by refining the formalism of our group. The previous formalism…
Refined form of the paper "Canonical formalism of the f(R)-type gravity in terms of Lie derivatives"
Yasuo Ezawa, Yoshiaki Ohkuwa
We refine the presentation of the previous paper of our group, Y.Ezawa et al., Class. Quantum Grav. {\bf 23} (2006), 3205 [arXiv:gr-qc/0507060]. In that paper, we proposed a canoni…
Third quantization of -type gravity II - General case -
Yoshiaki Ohkuwa, Yasuo Ezawa
In the previous paper we examined the third quantization of the -type gravity and studied the Heisenberg uncertainty relation of the universe in the example of . In…
