摘要：

We prove that a certain spinfoam model for Euclidean quantum general relativity, recently defined, is finite: all its all Feynman diagrams converge. The model is a variant of the Barrett-Crane model, and is defined in terms of a field theory over SO(4) x SO(4) x SO(4) x SO(4). (C) 2001 Published by Elsevier Science B.V.
