Further study on two fixed point iterative schemes for absolute value equations
摘要
In this paper, we reconsider two iterative methods for solving absolute value equations (AVE), which were proposed by Ali and Pan (Jpn J Ind Appl Math 40:303–314, 2023). Convergence results of the two iterative schemes and new sufficient conditions for the unique solvability of AVE are presented. In addition, for a special case, the optimal iteration parameters of the two algorithms are analyzed, respectively. Numerical results demonstrate our claims.
