Functional Distribution of the Tempered Anomalous Diffusion and Its Numerical Simulations
Prof. Wei-Hua Deng
School of Mathematics and Statistics, Lanzhou University

Tempered anomalous dynamics characterizes the very low transition between the anomalous and normal diffusion. Sometimes, because of the bounded physical space and/or the finite life span of particles, the tempered power law (instead of pure power law) jump length and/or waiting time distribution(s) in the CTRW model seems to be a more reasonable choice. In this talk, we will show the derivation of the PDE governing the functional distribution of the tempered anomalous diffusion. And the possible effective computational methods for the derived PDE will also be mentioned.
This is the joint work with Xiaochao Wu and Eli Barkai.
