Quantum Cosmology. I

Physical Review, 1969
Summary: The Hamiltonian methods of Arnowitt, Deser, and Misner can be applied to homogeneous cosmological models, and prove to be an efficient way both of constructing the Einstein equations and of studying their solutions. By using an appropriate form for the metric, one finds that the constraint equations for these models can be solved explicitly ...

Quantum Cosmology and the Cosmological Constant

1991
The origin of our universe and the small scale structure of spacetime lie deep in the realm of quantum theory, yet they seem to relate to the large scale features of the universe. The value of the cosmological constant is probably zero, but a small value related to a light particle mass is possible.

From Quantum Cosmology to Quantum Gravity

1983
The remarkable success of general relativity is marred by two fundamental difficulties at two apparently different scales. First the acausal character of the hot big bang cosmology is unacceptable because it leads to dynamical instabilities when extrapolated back to the Planck temperature.
