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 -discretized block is given, in the semiclassical limit, by a gaussian integral of a suitable -symbol. Possible developments of this result are discussed.
