任意阶Caputo-平稳函数的局部密度

Local density of Caputo-stationary functions of any order

Alessandro Carbotti, Serena Dipierro, Enrico Valdinoci

摘要:

我们表明,任何给定的功能可以近似任意精度的线性,时间分数方程的任何规定的顺序的解决方案。这将Claudia Bucur最近的一个结果推广到任何分数阶微分的情况,该结果是针对阶数小于1的时间分数阶导数得到的。此外,我们的结果也适用于$ψ$ -Caputo-固定的情况下,它将提供一个即将到来的论文中,我们将建立一般的近似结果,涉及各向异性叠加的经典,空间分数和时间分数扩散算子的任何顺序的积木。

英文摘要:

We show that any given function can be approximated with arbitrary precision by solutions of linear, time-fractional equations of any prescribed order. This extends a recent result by Claudia Bucur, which was obtained for time-fractional derivatives of order less than one, to the case of any fractional order of differentiation. In addition, our result applies also to the $ψ$-Caputo-stationary case, and it will provide one of the building blocks of a forthcoming paper in which we will establish general approximation results by operators of any order involving anisotropic superpositions of classical, space-fractional and time-fractional diffusions.
