摘要:

关于 M­-矩阵代数 Riccati 方程的理论与有效数值方法的研究是近年来的一个热点问题. 本文研究M­-矩阵代数 Riccati 方程最小非负解的存在性, 给出当系数矩阵为正则 M­矩阵时方程存在最小非负解的一个新证明, 这比原有证明要简单得多. 此外, 我们给出一个更广泛的条件来保证方程最小非负解的存在性, 这是现有结果的一个扩展.

Abstract:

Research on the theories and efficient numerical methods of M-­matrix algebraic Riccati equations (MARE) has become a hot topic in recent years. In this paper, we study the existence of minimal nonnegative solution for MARE and give a new proof to the existence of minimal nonnegative solution for the MARE associated with a regular M-­matrix, which is much simpler than the original proof. In addition, we give a wider condition to guarantee the existence of minimal nonnegative solution for the MARE, which is an extension of the existing results.
