Comment on "Mean First Passage Time for Anomalous Diffusion"
arXiv:cond-mat/0401072 · doi:10.1103/PhysRevE.69.033101
Abstract
We correct a previously erroneous calculation [Phys. Rev. E 62, 6065 (2000)] of the mean first passage time of a subdiffusive process to reach either end of a finite interval in one dimension. The mean first passage time is in fact infinite.
