Title
Colorful Helly-type theorems for the volume of intersections of convex bodies
Abstract
We prove the following Helly-type result. Let C1,…,C3d be finite families of convex bodies in Rd. Assume that for any colorful selection of 2d sets, Cik∈Cik for each 1≤k≤2d with 1≤i1<…<i2d≤3d, the intersection ⋂k=12dCik is of volume at least 1. Then there is an 1≤i≤3d such that ⋂C∈CiC is of volume at least d−O(d2).
