M-张量方程的不精确Newton方法

Inexact Newton Method for M-Tensor Equations

Dong-Hui Li, Hong-Bo Guan, Jie-Feng Xu

摘要:

我们首先研究M-张量方程的性质。特别地,我们证明了,如果方程的常数项是非负的,那么找到方程的非负解可以通过找到一个低维M-张量方程的正解来完成。然后,我们提出了一个不精确牛顿法,以找到一个正解的低维方程,并建立其整体收敛。我们还证明了该方法的收敛速度是二次的。最后,我们用数值实验来验证所提出的牛顿法。结果表明,所提出的牛顿法具有很好的数值性能。

英文摘要:

We first investigate properties of M-tensor equations. In particular, we show that if the constant term of the equation is nonnegative, then finding a nonnegative solution of the equation can be done by finding a positive solution of a lower dimensional M-tensor equation. We then propose an inexact Newton method to find a positive solution to the lower dimensional equation and establish its global convergence. We also show that the convergence rate of the method is quadratic. At last, we do numerical experiments to test the proposed Newton method. The results show that the proposed Newton method has a very good numerical performance.
