Creation of an Open Universe from Valley Bounce
Kazuya Koyama, Kayoko Maeda, Jiro Soda
It appears difficult to construct a simple model for an open universe based on the one bubble inflationary scenario. The reason is that one needs a large mass to avoid the tunnelin…

It appears difficult to construct a simple model for an open universe based on the one bubble inflationary scenario. The reason is that one needs a large mass to avoid the tunnelin…
Vacuum Wave Functional of Pure Yang-Mills Theory and Dimensional Reduction
Miyuki Kawamura, Kayoko Maeda, Makoto Sakamoto
Working in a Hamiltonian formulation with gauge and also in a path integral formulation, we show that the vacuum wave functional of four-dimensional pure Yang-Mills theor…
Strong Coupling Quantum Gravity and Physics beyond the Planck Scale
Kayoko Maeda, Makoto Sakamoto
We propose a renormalization prescription for the Wheeler-DeWitt equation of (3+1)-dimensional Einstein gravity and also propose a strong coupling expansion as an approximation sch…
Analysis of the Wheeler-DeWitt Equation beyond Planck Scale and Dimensional Reduction
T. Horiguchi, K. Maeda, M. Sakmaoto
We solve the Wheeler-DeWitt equation for {\it four}-dimensional Einstein gravity as an expansion in powers of the Planck mass by means of a heat kernel regularization. Our results…
Canonical treatment of two dimensional gravity as an anomalous gauge theory
T. Fujiwara, T. Tabei, Y. Igarashi +2
The extended phase space method of Batalin, Fradkin and Vilkovisky is applied to formulate two dimensional gravity in a general class of gauges. A BRST formulation of the light-con…
A new insight into BRST anomalies in string theory
T. Fujiwara, Y. Igarashi, J. Kubo +1
Using the generalized hamiltonian method of Batalin, Fradkin and Vilkovisky, we investigate the algebraic structure of anomalies in the Polyakov string theory that appear as the Sc…
