Issues in Quantized Fractal Space Time
  In recent years, the picture of discrete space time has been studied in the context of stochastic theory. There are a number of ramifications, which are briefly examined. We argue that the causality of physiics has its roots in the analyticity within the two dimensons of a fractal quantum path and further show how this picture has convergence wth quantum superstrings.
