The constraints as evolution equations for numerical relativity
Adrian P. Gentle, Nathan D. George, Arkady Kheyfets +1
The Einstein equations have proven surprisingly difficult to solve numerically. A standard diagnostic of the problems which plague the field is the failure of computational schemes…
The Issue of Time in Quantum Geometrodynamics
Nathan D. George, Adrian P. Gentle, Arkady Kheyfets +1
Standard techniques of canonical gravity quantization on the superspace of 3--metrics are known to cause insurmountable difficulties in the description of time evolution. We forwar…
Constraints in Quantum Geometrodynamics
Adrian P. Gentle, Nathan D. George, Arkady Kheyfets +1
We compare different treatments of the constraints in canonical quantum gravity. The standard approach on the superspace of 3--geometries treats the constraints as the sole carrier…
Off-Axis Neutrino Scattering in GRB Central Engines
Nathan D. George, Arkady Kheyfets, John M. McGhee +1
The search for an understanding of an energy source great enough to explain the gamma-ray burst (GRB) phenomena has attracted much attention from the astrophysical community since…
Time in Quantum Geometrodynamics
Warner A. Miller, Arkady Kheyfets
We revisit the issue of time in quantum geometrodynamics and suggest a quantization procedure on the space of true dynamic variables. This procedure separates the issue of quantiza…
