求解含奇异源项的时间分数阶扩散方程

Solving time-fractional diffusion equations with singular source term

Yavar Kian, Eric Soccorsi

摘要:

本文研究了具有含时奇异源项的时间分数阶扩散方程。当时间分数阶导数的阶数是多项的、分布的或空间相关的时,只要源项的时间相关性是分布的,我们证明了系统存在唯一的弱解,且弱解满足Duhamel表示.

英文摘要:

This article deals with time-fractional diffusion equations with time-dependent singular source term. Whenever the order of the time-fractional derivative is either multi-term, distributed or space-dependent, we prove that the system admits a unique weak solution enjoying a Duhamel representation, provided that the time-dependence of the source term is a distribution.
