Web21 sep. 2024 · Helly's selection theorem. Here is the proof from my lecture notes; I expect it is Helly's original proof. Today the theorem would perhaps be seen as an instance of … WebHelly's theorem is a statement about intersections of convex sets. A general theorem is as follows: Let C be a finite family of convex sets in Rn such that, for k ≤ n + 1, any k members of C have a nonempty intersection. Then the intersection of all members of C is nonempty.
