摘要: 用拓扑度理论研究绝对值方程可解的充分条件, 结果表明, 一个绝对值方程或者存在解或者存在例外族. 运用该结论, 进一步得到: 当矩阵A为广义三次矩阵时, 绝对值方程不存在例外族, 从而绝对值方程有解.

关键词: 广义三次矩阵, 绝对值方程, 例外族

Abstract: We used the theory of topological degree to study a sufficient condition for solvability of absolute value equation. The results show that the absolute value equation has a solution or has a exceptional family of elements. Furthermore, by this conclusion, we obtain the noexistence of the exceptional family of elements, when matrix A is a generalized cubic matrix, so the absolute value equation has a solution.

Key words: absolute value equation, generalized cubic matrix, exceptional family of elements
