摘要本文讨论了由一个内点观测值确定时间分数阶扩散方程分数阶的反问题。我们通过Mittag-Leffler函数和特征函数展开给出了解的表示,由此建立了分数阶系统在内点关于测量数据的Lipschitz稳定性.
Abstract This paper deals with an inverse problem of the determination of the fractional order in time-fractional diffusion equations from one interior point observation. We give a representation of the solution via the Mittag-Leffler function and eigenfunction expansion, from which the Lipschitz stability of the fractional order with respect to the measured data at the interior point is established.
