A new concave minimization algorithm for the absolute value equation solution

Optimization Letters, 2021
In this paper, we study the absolute value equation (AVE) Ax- b= | x|. One effective approach to handle AVE is by using concave minimization methods. We propose a new method based on concave minimization methods. We establish its finite convergence under

On the Unique Solvability of the Absolute Value Equation

Journal of Optimization Theory and Applications, 2015
The authors consider the absolute value equation \(Ax+B|x|=b\) for matrices \(A,B\in \mathbb R^{n\times n}\) and investigate its unique solvability in the case \(B=I\) and for \(A\) diagonally dominant, connected to \(M\)-matrices or being positive definite.

A class of maximum-based iteration methods for the generalized absolute value equation

Applied Mathematics Letters
In this paper, by using $|x|=2\max\{0,x\}-x$, a class of maximum-based iteration methods is established to solve the generalized absolute value equation $Ax-B|x|=b$. Some convergence conditions of the proposed method are presented.

Difference equations with absolute values

Journal of Difference Equations and Applications, 2005
We study a class of multiparameter difference equations that contain the absolute value of a difference. Using two different semiconjugate factorizations, we obtain precise information about the solutions of these equations for various ranges of parameter values.
