非均匀连续时间随机游动模型的连续极限

Continuous limits of Heterogeneous Continuous Time Random Walk model

Liubov Tupikina

摘要:

连续时间随机游走模型是研究和模拟非均质结构(如无序或多孔介质)中扩散过程的通用分析形式。本文研究了异质连续时间随机游动模型在图上跳跃时的连续极限。我们应用广义主方程的概念来研究网络上的非均匀连续时间随机游动。根据对等待时间分布的不同解释,广义主方程给出了不同形式的连续方程。

英文摘要:

Continuous time random Walk model has been versatile analytical formalism for studying and modeling diffusion processes in heterogeneous structures, such as disordered or porous media. We are studying the continuous limits of Heterogeneous Continuous Time Random Walk model, when a random walk is making jumps on a graph within different time-length. We apply the concept of a generalized master equation to study heterogeneous continuous-time random walks on networks. Depending on the interpretations of the waiting time distributions the generalized master equation gives different forms of continuous equations.
