摘要:

通过对绝对值方程的光滑形式构造同伦方程, 证明了同伦路径的存在性、 有界性和收敛性, 得到了绝对值方程解存在的一个条件, 该条件比现有条件更弱.

关键词: 绝对值方程, 同伦方法, 同伦路径

Abstract:

The homotopy equation was constructed for absolute value equation, the existence, boundedness and convergence were proved, and an existence condition of a solution of absolute value equation was obtained. This condition is weaker than the one in the literature.

Key words: absolute value equation, homotopy method, homotopy path
