There is a hierarchy of structure conditions for convex sets. We study a recently defined condition called locally nonconical convexity (abbreviated LNC). Is is easy to show that every strictly convex set is LNC, as are half-spaces and finite intersections of sets of either of these types, but many more sets are LNC. For instance, every zonoid (the range of a nonatomic vector-valued measure) is LNC. However, there are no infinite-dimensional compact LNC sets.
