A. Torres-Hernandez, F. Brambila-Paz, U. Iturrarán-Viveros, R. Caballero-Cruz

AI总结:

本文提出获取分数阶 Newton-Raphson 方法的收敛阶,简化构造 Riemann-Liouville 分数阶算子,并利用 Aitken 方法加速其收敛,展示了结合两者的实验结果。

摘要:

在以下文档中,我们提出了一种获取分数阶 Newton-Raphson (F N-R) 方法收敛阶的方法。当导数阶 $α$ 不为 1 时,该方法似乎至少具有线性收敛阶。我们介绍了一种构造 Riemann-Liouville (R-L) 分数阶算子、分数阶积分和分数阶导数的简化方法,并给出了其在不同函数上应用的示例。此外,我们还介绍了 Aitken 方法,并解释了为何它能够加速迭代方法的收敛,最后展示了将 Aitken 方法应用于 F N-R 方法所获得的结果。

英文摘要:

In the following document, we present a way to obtain the order of convergence of the Fractional Newton-Raphson (F N-R) method, which seems to have an order of convergence at least linearly for the case in which the order $α$ of the derivative is different from one. A simplified way of constructing the Riemann-Liouville (R-L) fractional operators, fractional integral and fractional derivative, is presented along with examples of its application on different functions. Furthermore, an introduction to the Aitken's method is made and it is explained why it has the ability to accelerate the convergence of the iterative methods, to finally present the results that were obtained when implementing the Aitken's method in the F N-R method.
