Quantum gravity as a group field theory: a sketch
arXiv:gr-qc/0512048 · doi:10.1088/1742-6596/33/1/030
Abstract
We give a very brief introduction to the group field theory approach to quantum gravity, a generalisation of matrix models for 2-dimensional quantum gravity to higher dimension, that has emerged recently from research in spin foam models.
