分数阶扩散方程的强最大值原理及其在源反问题中的应用

Strong maximum principle for fractional diffusion equations and an application to an inverse source problem

Yikan Liu, William Rundell, Masahiro Yamamoto

摘要:

强最大值原理是抛物型方程的一个显著特征,它有望被分数阶扩散方程部分继承。基于相应的弱最大值原理,本文建立了含Caputo导数的时间分数阶扩散方程的一个强最大值原理,它比抛物型方程的弱.作为一个直接的应用,我们给出了一个相关的反源问题的非齐次项的时间分量的确定的唯一性结果。

英文摘要:

The strong maximum principle is a remarkable characterization of parabolic equations, which is expected to be partly inherited by fractional diffusion equations. Based on the corresponding weak maximum principle, in this paper we establish a strong maximum principle for time-fractional diffusion equations with Caputo derivatives, which is slightly weaker than that for the parabolic case. As a direct application, we give a uniqueness result for a related inverse source problem on the determination of the temporal component of the inhomogeneous term.
