The piecewise linear equation system z- A| z| = b is called an absolute value equation. In this note we consider two solvers for uniquely solvable instances of the latter problem, one direct, one semi-iterative. We slightly extend the existing correctness, resp. convergence, results for the latter algorithms and provide numerical tests.en1862-4480202261663 - 16731663 - 1673Springerhttps://creativecommons.org/licenses/by/4.0/Absolute value equationPiecewise linear systemSign-real spectral radiusLinear complementarity problemsInformatikMathematikJournal Article10.15480/882.443710.1007/s11590-021-01837-710.15480/882.4437Other
