Abstract
The renormalization structure of two-dimensional quantum gravity is in vestigated in a covariant gauge. One-loop divergences of the effective action are calculated. All the surface divergent terms are taken into account thus completing previous one-loop calculations of the theory. It is shown that the on-shell effective action contains only surface divergences. The off-shell renormalizability of the theory is discusse d and classes of renormalizable dilaton and Maxwell potentials are fou nd.
