That is, if ‖ y ‖ 1 + 2 δ, then the sets ‖ x ‖ 1 and ‖ x − y ‖ < δ are disjoint. Hence the complement of the "closed" unit ball is open and the "closed" unit ball really is closed.

The intersection of a finite number of closed half-spaces is a convex polyhedron. The faces of a convex body are its intersections with the supporting hyperplanes. A face is a convex body of lower dimension. The convex body is considered to be its own $n$-dimensional face.
