若干分段线性解算器的收敛性结果

Convergence results for some piecewise linear solvers

Manuel Radons, Siegfried M. Rump

摘要:

设$A$是一个实$n\times n$矩阵,而$z,b\in \mathbb R^n$ .分段线性方程系统$z-A\vert z\vert = b$被称为\textit{absolute value equation}。我们考虑两个解决这个问题,一个直接的,一个半迭代,并延长他们以前已知的收敛范围。

英文摘要:

Let $A$ be a real $n\times n$ matrix and $z,b\in \mathbb R^n$. The piecewise linear equation system $z-A\vert z\vert = b$ is called an \textit{absolute value equation}. We consider two solvers for this problem, one direct, one semi-iterative, and extend their previously known ranges of convergence.
