Abstract:
It is shown how the expectation value of a spin network can be
computed in discretized spacetime.
To calculate this quantity, we use a spin foam model, which is a
discrete path integral approach to quantum gravity.
The expectation value can be perturbatively computed by applying
the Freidel-Krasnov-Miković (FKM) model.
