Proper time is stochastic time in 2d quantum gravity
We show that proper time, when defined in the quantum theory of 2d gravity, becomes identical to the stochastic time associated with the stochastic quantization of space. This observation was first…
Quantum gravity represented as dynamical triangulations
We discuss the attempts to represent quantum gravity in more than two dimensions as a sum over random triangulations. The results are mainly of numerical nature, obtained by Monte Carlo simulations…

Quantum gravity as sum over spacetimes
A major unsolved problem in theoretical physics is to reconcile the classical theory of general relativity with quantum mechanics. These lectures will deal with an attempt to describe quantum gravity…

4D simplicial quantum gravity with a nontrivial measure.
We study 4D simplicial quantum gravity in the dynamical triangulation approach with a nontrivial class of measures. We find that the measure contribution plays an important role, influencing the…
