摘要: 用同伦方法讨论线性互补问题解存在的条件. 首先, 给出与线性互补问题等价的绝对值方程, 然后对绝对值方程构造同伦方程, 并借助于该同伦方程给出绝对值方程解存在的一个正则性条件, 该正则性条件可转化为线性互补问题解存在的条件.

关键词: 绝对值方程, 同伦方法, 线性互补问题

Abstract: The homotopy method was used to discuss the existence conditions of a solution of linear complementarity problems. First, 
the absolute value equations equivalent to linear complementarity problem was given. Then, the homotopy equation was constructed for the absolute value equation, and a regularity condition for the existence of solutions of absolute value equations was given by means of this homotopy equation, which  can be transformed into a condition for the existence of solutions of linear complementarity problems.

Key words: absolute value equation, homotopy method, linear complementarity problem
