Abstract

We propose a model which represents a four-dimensional version of Ponzano and Regge's three-dimensional euclidean quantum gravity. In particular we show that the exponential of the euclidean Einstein-Regge action for a 4D discretized block is given, in the semiclassical limit, by a gaussian integral of a suitable 12 j-symbols. Possible developments of this results are discussed.
