无标度度量网络扩散过程的均匀化

Diffusion Processes Homogenization for Scale-Free Metric Networks

Fernando A. Morales, Daniel E. Restrepo

摘要:

本文讨论了无标度量图上扩散过程的均匀化分析。沿着度量图的边缘的扩散系数的振荡诱导在全球系统中的内部奇异性,连同大型网络的高复杂性构成了直接分析问题的重大困难。同时,这些事实也表明,同质化作为一种可行的方法来建模的全局行为的问题。为此,我们研究了一系列的边界问题上的度量图的嵌套集合定义的渐近行为。本文给出了该问题的弱变分形式、解的收敛性分析和数值试验。

英文摘要:

This work discusses the homogenization analysis for diffusion processes on scale-free metric graphs, using weak variational formulations. The oscillations of the diffusion coefficient along the edges of a metric graph induce internal singularities in the global system which, together with the high complexity of large networks constitute significant difficulties in the direct analysis of the problem. At the same time, these facts also suggest homogenization as a viable approach for modeling the global behavior of the problem. To that end, we study the asymptotic behavior of a sequence of boundary problems defined on a nested collection of metric graphs. This paper presents the weak variational formulation of the problems, the convergence analysis of the solutions and some numerical experiments.
