Consistent discretizations as a road to quantum gravity
Rodolfo Gambini, Jorge Pullin
We present a brief description of the ``consistent discretization'' approach to classical and quantum general relativity. We exhibit a classical simple example to illustrate the ap…
Consistent discretization and canonical classical and quantum Regge calculus
Rodolfo Gambini, Jorge Pullin
We apply the ``consistent discretization'' technique to the Regge action for (Euclidean and Lorentzian) general relativity in arbitrary number of dimensions. The result is a well d…
Classical and quantum general relativity: a new paradigm
Rodolfo Gambini, Jorge Pullin
We argue that recent developments in discretizations of classical and quantum gravity imply a new paradigm for doing research in these areas. The paradigm consists in discretizing…
Consistent discretizations: the Gowdy spacetimes
Rodolfo Gambini, Marcelo Ponce, Jorge Pullin
We apply the consistent discretization scheme to general relativity particularized to the Gowdy space-times. This is the first time the framework has been applied in detail in a no…
Discrete space-time
Rodolfo Gambini, Jorge Pullin
We review recent efforts to construct gravitational theories on discrete space-times, usually referred to as the ``consistent discretization'' approach. The resulting theories are…
