For some families of this type, we give upper bounds on the size of a finite set intersecting all ... 展开 In this paper, we consider finite families of convex sets in R-d such that every d or fewer sets of the family have a common point. For some families of this type, we give upper bounds on the size of a finite set intersecting all sets of the family. 收起
