| 摘 要： | 对Ｒ＾ｎ的偶点集，枰分它的超平面全体的模空间约化到ＲＰ＾ｎ上紧化再作形变收缩，包含了一个ＲＰ＾ｎ－１，由Ｐｏｉｎｃａｒｅ对偶及拓朴相交性质可知对Ｒ＾ｎ中ｎ组处于一般位置的偶点集，有一个超平面将之同时平分。

| Abstract: | For a finite set in R n with even
cardinal,the supersurfaces split it into two equally part formes a moduli space.The moduli
space can be reduced into RP n ,its compactification contract to a sub complex,which
can be viewed as RP n-1 in RP n .Now,Poincare dual and the intersection property
applied,the author finally get the conclusion,which states there is a supersurface split the
generally sitted n ple even point set in R n into two equally part simultaneousy. |
