广义扩散方程与波动方程:最新进展

Generalised Diffusion and Wave Equations: Recent Advances

Trifce Sandev, Ralf Metzler, Aleksei Chechkin

摘要:

我们提出了一个简短的概述,最近的结果在扩散和波动方程的理论与广义导数算子。我们给出了一般的例子,这样的广义扩散和波动方程,其中包括时间分数,分布顺序,回火时间分数扩散和波动方程。这样的方程表现出多尺度的时间行为,这使得它们适合于描述不同的扩散制度和特性的交叉动力学在复杂系统。

英文摘要:

We present a short overview of the recent results in the theory of diffusion and wave equations with generalised derivative operators. We give generic examples of such generalised diffusion and wave equations, which include time-fractional, distributed order, and tempered time-fractional diffusion and wave equations. Such equations exhibit multi-scaling time behaviour, which makes them suitable for the description of different diffusive regimes and characteristic crossover dynamics in complex systems.
