Spin Foam Models of Quantum Spacetime
Daniele Oriti
Spin foam models are a new approach to a formulation of quantum gravity which is fully background independent, non-perturbative, and covariant, in the spirit of path integral formu…

Causality in spin foam models for quantum gravity
Etera R. Livine, Daniele Oriti
We describe how the Barrett-Crane spin foam model defines transition amplitudes for quantum gravity states and how causality can be consistently implemented in it.
