Abstract

We prove that for any collection F of n ≥ 2 pairwise disjoint compact convex sets in the plane there is a pair of sets A and B in F such that any line that separates A from B separates either A or B from a subcollection of F with at least n/18 sets.

凸多边形与凸分离
证明了对于平面上n≥2对不相交紧凸集的任何集合F,在F中存在一对集合a和B,使得任何一条将a与B分开的直线将a或B从F的子集合中分离出至少n/18个集合。
