A finite spin-foam-based theory of three and four dimensional quantum gravity
Rodolfo Gambini, Jorge Pullin
Starting from Ooguri's construction for theory in three (and four) dimensions, we show how to construct a well defined theory with an infinite number of degrees of freedom. Th…
Close limit evolution of Kerr-Schild type initial data for binary black holes
Olivier Sarbach, Manuel Tiglio, Jorge Pullin
We evolve the binary black hole initial data family proposed by Bishop {\em et al.} in the limit in which the black holes are close to each other. We present an exact solution of t…
Lorentz violations in canonical quantum gravity
Rodolfo Gambini, Jorge Pullin
This is a summary of a talk given at the CP01 meeting on possible Lorentz anomalies in canonical quantum gravity. It briefly reviews some initial explorations on the subject that h…
Consistent discretizations for classical and quantum general relativity
Rodolfo Gambini, Jorge Pullin
We consider discretizations of the Einstein action of general relativity such that the resulting discrete equations of motion form a consistent constrained system. Upon ``spin foam…
A cure for unstable numerical evolutions of single black holes: adjusting the standard ADM equations
Bernard Kelly, Pablo Laguna, Keith Lockitch +4
Numerical codes based on a direct implementation of the standard ADM formulation of Einstein's equations have generally failed to provide long-term stable and convergent evolutions…
