摘要: 对绝对值方程的等价形式广义线性互补问题, 构造组合同伦方程, 并基于该同伦方程得到了广义线性互补问题解存在的一个条件, 该条件与目前常用的区间矩阵的正则性不同. 实例分析表明, 该条件不比区间的正则性条件强, 从而获得了绝对值方程问题解存在的一个新条件.

Abstract: A combined homotopy equation was constructed for solving the generalized linear complementarity problem, which was equivalent to the absolute value equation,  an existence condition of a solution of the generalized linear complementarity problem was obtained based on the homotopy equation,  and this condition was different from that of the usual interval matrix.  An example shows that this condition is not stronger than the regularity condition of the interval, so we obtain a new existence condition of a solution of absolute value equation.

Key words: absolute value equation, homotopy method, column sufficient matrix
