Phys. Rev. D 54, 7902–7905 (1996)Summation over histories for the Friedmann universeReceived 15 April 1996; published in the issue dated 15 December 1996 An explicit path-integral treatment of the Friedmann minisuperspace model with minimally coupled massless scalar fields is presented. Unlike the usual approach where a semiclassical approximation is used, an exact path integration is performed. © 1996 The American Physical Society URL:
