Helly space is a concept from topology and discrete geometry, named after the mathematician Eduard Helly. It is primarily associated with the study of intersections of convex sets. In mathematical terms, a Helly space is a topological space where a certain intersection property holds. Specifically, in a Helly space, if a collection of convex sets has the property that every finite subcollection of them has a non-empty intersection, then there exists a non-empty intersection for the entire collection.
