Piecewise flat metrics and quantum gravity

We introduce a piecewise metric for a Regge triangulation of a spacetime and describe its properties in the Eucledean and in the Minkowski case. Then we show how to define the path integral for the wavefunction and the propagator in the case of the triangulations which correspond to the minisuperspace models.
