geometry , a subset of a euclidean space , or more generally an affine space over the reals , is convex if, given any two points, it contains the whole line segment that joins them. equivalently, a convex set or a convex region is a subset that intersect every line into a single line segment (possibly empty
is the case r = , this property characterizes convex sets. such an affine combination is called a convex combination of u , ..., ur. intersections and unions[ edit ] the collection of convex subsets of a vector space, an affine space, or a euclidean space has the following properties: [ ] [ ] the empty...
