非线性代数方程的广义线性化:一种创新方法

Generalized linearization of nonlinear algebraic equations: an innovative approach

W. Chen

AI总结:

本文提出将非线性问题视为不适定线性系统,通过将非线性项表示为线性无关变量,将n维非线性系统扩展为n(n+1)/2维线性系统,从而可应用广义逆矩阵和奇异值分解进行非线性计算与分析。

摘要:

基于本文作者先前提出的通用非线性数值模拟的矩阵表达,本文提出了一种新颖的非线性计算与分析哲学。非线性问题被视为一个不适定的线性系统。这样,所有非线性代数项转而表示为线性无关的变量。因此,一个n维非线性系统可以扩展为n(n+1)/2维空间中的线性系统。这为将矩阵的广义逆应用于非线性系统的计算提供了可能性。同时,通过这种方法,奇异值分解(SVD)可以直接用于非线性分析。

英文摘要:

Based on the matrix expression of general nonlinear numerical analogues presented by the present author, this paper proposes a novel philosophy of nonlinear computation and analysis. The nonlinear problems are considered an ill-posed linear system. In this way, all nonlinear algebraic terms are instead expressed as Linearly independent variables. Therefore, a n-dimension nonlinear system can be expanded as a linear system of n(n+1)/2 dimension space. This introduces the possibility to applying generalized inverse of matrix to computation of nonlinear systems. Also, singular value decomposition (SVD) can be directly employed in nonlinear analysis by using such a methodology.
