Abstract

Abstract A generalised action for two-dimensional quantum gravity is considered. This includes, in addition to the Einstein-Hilbert action near two dimensions, a term imposing the constancy of the scalar curvature R. The propagators have no poles in ϵ( d=2− ϵ) and the theory can be made on-shell finite by tuning some parameters. We argue that the anomalous dimensions of certain operators do not get renormalised. This is in agreement with the exact solution of the Liouville theory supplemented with a constraint expressing the constancy of R.
