A classical result of Eckhoff in 1988 provided an optimal fractional Helly theorem for axis-aligned boxes, which are Cartesian products of line segments.

If a family of nonempty sets has an empty intersection, its Helly number must be at least two, so the smallest k for which the k-Helly property is nontrivial is k = 2. The 2-Helly property is also known as the Helly property. A 2-Helly family is also known as a Helly family.

In particular, the center C ( G ) of a C 4 -free Helly graph G is convex and it has diameter at most 3 and radius at most 2 [ 23 , 20 ] .
WebThe Helly property generalizes this theorem for families of sets of any kind. A family of sets satis es the Helly property, or simply is a Helly family, if for every subfamily Fof pairwise intersecting sets there is an element common to all the sets in F.
