Papers

1. Action integrals and partition functions in quantum gravityPhysical review. D. Particles, fields, gravitation, and cosmology/Physical review. D. Particles and fields · 1977 · 3,466 citations

   One can evaluate the action for a gravitational field on a section of the complexified spacetime which avoids the singularities. In this manner we obtain finite, purely imaginary values for the actions of the Kerr-Newman solutions and de Sitter space.…

2. Cosmological event horizons, thermodynamics, and particle creationPhysical review. D. Particles, fields, gravitation, and cosmology/Physical review. D. Particles and fields · 1977 · 3,199 citations

   It is shown that the close connection between event horizons and thermodynamics which has been found in the case of black holes can be extended to cosmological models with a repulsive cosmological constant. An observer in these models will have…
