摘要：

We give a precise definition of the functional integrals involved by means of different discretization prescriptions. The value of the functional integral is prescription dependent and this leads to a variety of representations with different Lagrangians. We discuss general covariance and we derive in a unified way, all the lagrangians proposed in the literature together with their associated discretizations. We make also a critical examination of previous results. © 1979 Società Italiana di Fisica.
