摘要
针对一类绝对方程利用方程理论、射影变换和行列式理论,在引入几个基本定义的基础上,研究了绝对值方程表示的几何图像(凹四边形)及其具有性质,并对此进行简单应用.
Based on a class of absolute value equations, and by using the equation theory, projective transformation and determinant theory,this paper introduces some basic concepts and researches the geometric image(Concave quadrilateral) represented by a class of absolute value equations. Its properties are simply studied and applied.
