We prove the following Helly-type result. Let be finite families of convex bodies in . Assume that for any colorful selection of 2d sets, for each with , the intersection is of volume at least 1. Then there is an such that is of volume at least .

凸体相交体积的彩色Helly型定理
我们证明以下Helly型结果。让 是凸凸体的有限族 。假设对于2d集的任何彩色选择, 每个 与 , 十字路口 的体积至少为1。然后有一个 这样 至少有数量 。
