Abstract: (Elsevier)

In two spacetime dimensions a c-number (“Schwinger term”, “central charge”) is allowed in the algebra of surface deformations. A non-trivial analog of gravitation theory in two dimensional spacetime is built upon this fact, with the inverse of the central charge playing the role of the gravitational constant. Classically the analog with gravitation theory is only partial in that the hamiltonian constraints cannot be imposed, but it becomes complete at the quantum level.
