Breen M (1996) A Helly-type theorem … In mathematics, Helly's selection theorem (also called the Helly selection principle) states that a uniformly bounded sequence of monotone real functions admits a convergent subsequence. In other words, it is a sequential compactness theorem for the space of uniformly bounded monotone functions. It is named for the Austrian mathematician Eduard Helly. A more general version of the theorem asserts compactness of the space BVloc of functions locally of bounded t…

It was discovered by Eduard Helly in 1913, but not published by him until 1923, by which time alternative proofs by Radon (1921) and König (1922) had already appeared. Helly's theorem gave rise to the notion … Meer weergeven Let X1, ..., Xn be a finite collection of convex subsets of R , with n ≥ d + 1. If the intersection of every d + 1 of these sets is nonempty, then the whole collection has a nonempty intersection; that is, Meer weergeven We prove the finite version, using Radon's theorem as in the proof by Radon (1921). The infinite version then follows by the finite intersection property Meer weergeven For every a > 0 there is some b > 0 such that, if X1, ..., Xn are n convex subsets of R , and at least an a-fraction of (d+1)-tuples of the sets have a point in common, then a … Meer weergeven The colorful Helly theorem is an extension of Helly's theorem in which, instead of one collection, there are d+1 collections of convex subsets of R .
