Consistent discretizations and quantum gravity
Rodolfo Gambini, Jorge Pullin
We review a recent proposal for the construction of a quantum theory of the gravitational field. The proposal is based on approximating the continuum theory by a discrete theory th…

Making classical and quantum canonical general relativity computable through a power series expansion in the inverse cosmological constant
Rodolfo Gambini, Jorge Pullin
We consider general relativity with a cosmological constant as a perturbative expansion around a completely solvable diffeomorphism invariant field theory. This theory is the $Λ\to…

Yang-Mills analogues of the Immirzi ambiguity
R. Gambini, O. Obregon, J. Pullin
We draw parallels between the recently introduced ``Immirzi ambiguity'' of the Ashtekar-like formulation of canonical quantum gravity and other ambiguities that appear in Yang-Mill…
