摘要：

A possible definition of path integrals for string theory is studied, based on a discretized version of Polyakov's generating functional. The finite resolution of string theory, as opposed to the infinite resolution in particle theory, clearly emerges from a renormalization group type analysis. We derive the existence of a minimum physical length (∼10-33cm) and generalized form of the uncertainty principle, and discuss some of their consequences. © 1990.
