Abstract

The formulation of general relativity in terms of surface deformations and its extension to supergravity are briefly reviewed. The role of the spacetime signature e is discussed. It is pointed out that ε may be used as a perturbation parameter. The “free” theory corresponds to ε = 0, which is halfway between hyperbolic (ε = −1) and Euclidean (ε = +1) spacetime.
