Phys. Rev. Lett. 70, 1908–1911 (1993)4D simplicial quantum gravity with a nontrivial measureReceived 5 October 1992; published in the issue dated 29 March 1993 We study 4D simplicial quantum gravity in the dynamical triangulation approach with a nontrivial class of measures. We find that the measure contribution plays an important role, influencing the phase diagram and the nature of the (possible) critical theory. We discuss how the lattice theory could be used to fix the quantum measure in a nonambiguous way. © 1993 The American Physical Society URL:
