Schild Action and Space-Time Uncertainty Principle in String Theory
Abstract
We discuss the meaning of the Schild action from the viewpoint of a possible space-time uncertainty principle in string theory and present an interpretation of the Schild action which points toward a derivation of superstring theory as a theory of quantized space-time where the squared string scale, l(2}_{s) ~ α', plays the role of the minimum quantum for space-time areas. A tentative approach toward such a goal is proposed, based on a microcanonical formulation of a large N supersymmetric matrix model.
