Abstract: (Elsevier)
Expressed in terms of zweibein and spin-connection, non-einsteinian gravity in d = 2 resembles a gauge theory with noncompact group and with nonpolynomial self-interactions. We show that this theory, nevertheless, is renormalizable because an infinite set of counterterms in the effective action may be expressed by one renormalizable quantity. Our analysis is based upon the use of a light-cone gauge where the UV behaviour, but especially also severe IR problems are more amenable to analysis than in a covariant gauge.
