摘要：

Motivated by recent suggestions that renormalisation constants evaluated at the fixed point of the epsilon-expansion for two-dimensional quantum gravity might reproduce Polyakov's exact two-dimensional results, we discuss the perturbative calculation of the effective action for quantum gravity in (2 - epsilon) dimensions. We show that the theory is non-renormalizable at two-loop order.
