Feynman diagams coupled to three-dimensional quantum gravity
arXiv:gr-qc/0502048 · doi:10.1088/0264-9381/23/1/008
Abstract
A framework for quantum field theory coupled to three-dimensional quantum gravity is proposed. The coupling with quantum gravity regulates the Feynman diagrams. One recovers the usual Feynman amplitudes in the limit as the cosmological constant tends to zero.
