Ad-多面体是一个ad-维集,它是有限个点的凸包。AD-多面体是简单的,只要每个顶点都精确地与D条边相交。有人推测,对于简单的多面体{fx121-1},其中f是多面体的I维面的个数。在这篇文章中,我们证明了不等式(I)对所有的简单多面体都成立。
Ad-polytope is ad-dimensional set that is the convex hull of a finite number of points. Ad-polytope is simple provided each vertex meets exactlyd edges. It has been conjectured that for simple polytopes {fx121-1} wherefi is the number ofi-dimensional faces of the polytope. In this paper we show that inequality (i) holds for all simple polytopes.
