分数阶 Newton-Raphson 方法及其变体用于求解非线性系统

Fractional Newton-Raphson Method and Some Variants for the Solution of Non-linear Systems

A. Torres-Hernandez, F. Brambila-Paz

AI总结:

本文提出基于分数阶 Newton-Raphson 方法的变体,通过将分数阶导数的阶数设为函数,在实初始条件下求解复空间中的非线性系统,实现保证二阶或线性收敛阶并避免不连续性。

摘要:

以下文档提出了一些适用于单变量和多变量的新型数值方法,这些方法利用分数阶导数,允许在实初始条件下求解复空间中的某些非线性系统。这些方法起源于分数阶 Newton-Raphson 方法,但与后者不同的是,此处提出的分数阶导数的阶数是函数。在第一种方法中,使用一个函数来保证(至少)二阶的收敛阶;而在其他方法中,使用一个函数来避免使用常数的分数阶导数时产生的不连续性,由此使得这些方法能够具有至多(至少)线性的收敛阶。

英文摘要:

The following document presents some novel numerical methods valid for one and several variables, which using the fractional derivative, allow to find solutions for some non-linear systems in the complex space using real initial conditions. The origin of these methods is the fractional Newton-Raphson method but unlike the latter, the orders of fractional derivatives proposed here are functions. In the first method, a function is used to guarantee an order of convergence (at least) quadratic, and in the others, a function is used to avoid the discontinuity that is generated when the fractional derivative of the constants is used, and with this, it is possible that the methods have at most an order of convergence (at least) linear.
