分布阶导数与松弛模式

Distributed Order Derivatives and Relaxation Patterns

Anatoly N. Kochubei

摘要:

我们考虑方程的形式$(D_{(ρ)}u)(t)=-λu(t)$,$t>0$,其中$λ>0$,$D_{(ρ)}$是一个分布阶导数,这是Caputo-Dzhrbashyan分数阶导数$α$,集成在$α\in (0,1)$关于一个积极的措施$ρ$。这些方程用于建模异常,非指数松弛过程。在这项工作中,我们研究上述方程的解的渐近行为,依赖于测量$ρ$的性质。

英文摘要:

We consider equations of the form $(D_{(ρ)}u)(t)=-λu(t)$, $t>0$, where $λ>0$, $D_{(ρ)}$ is a distributed order derivative, that is the Caputo-Dzhrbashyan fractional derivative of order $α$, integrated in $α\in (0,1)$ with respect to a positive measure $ρ$. Such equations are used for modeling anomalous, non-exponential relaxation processes. In this work we study asymptotic behavior of solutions of the above equation, depending on properties of the measure $ρ$.
