摘要:

我们获得了Riemann-Liouville分数阶积分算子的一个新分解,该分解以整数阶导数的级数形式表示。新公式对$C^n$类函数($n \in \mathbb{N}$)有效,并使我们能够开发具有已知误差估计的合适数值逼近。文中说明了所得结果在求解分数阶积分方程和分数阶变分问题中的实用性。

英文摘要:

We obtain a new decomposition of the Riemann-Liouville operators of fractional integration as a series involving derivatives (of integer order). The new formulas are valid for functions of class $C^n$, $n \in \mathbb{N}$, and allow us to develop suitable numerical approximations with known estimations for the error. The usefulness of the obtained results, in solving fractional integral equations and fractional problems of the calculus of variations, is illustrated.
