射影空间对偶原理的研究

Research on the Dual Fundamentals of Projective Space

射影空间是对偶结构 ,用齐次射影坐标研究了射影空间的对偶原理 ,从而揭示出射影空间里互相对偶的点与平面的坐标之间的内在联系 .

Using homogeneous projective coordinate,this paper presents a researches of the dual of projective space and reveals the essence of dual fundamentals of projective space the same coordinate represents both point and plane,and there is a dual relation in the point and plane.
