Abstract
Quantum conformal fluctuations are analyzed using the path integral approach. Conformal fluctuations are introduced in a classical Robertson-Walker universe with a massless scalar field as a source. It is shown that the conformal fluctuations diverge at the classical singularity. However, the effective metric still retains the singularity. Some other aspects of introducing the scalar field in this quantum gravity model are briefly discussed.
