Abstract

Stability estimates of Hölder type for the problem of evaluating the Caputo fractional derivative are obtained. This ill-posed problem is regularized by a Tikhonov-type method, which guarantees error estimates of Hölder type. Numerical results are presented to confirm the theory.

卡普托分数导数的提霍诺夫式正则化方法

针对卡普托分数导数的求值问题，获得了霍尔德类型的稳定性估计。这个问题是由一种 Tikhonov 型方法正则化的，它保证了霍尔德类型的误差估计。数值结果证实了这一理论。
