摘要：
In recent years the Continuous Time Random Walk (CTRW) has been used to model anomalous diffusion in a variety of complex systems. Since this process is non-Markovian, the knowledge of single time probability distributions is not sufficient to characterize the CTRW. Using the method of subordination we construct an extension of the Wiener path integral for Brownian motion to CTRW processes. This contribution is a step towards a path integral formulation of CTRWs.
