Entropy using path integrals for quantum black hole models

Canonical quantum gravity has been used in the search for eigenvalue equati ons that could describe black holes. In this paper we choose one of the sim plest of these quantum equations to show how the usual Feynman's path integ ral approach can be applied to get the corresponding statistical properties . We get a logarithmic correction to the Bekenstein Hawking entropy as alre ady obtained by other authors by other means.
