In a normed space, a set S is called a Chebyshev set iff ∀x ∈ X, there exists a unique s ∈ S s.t. kx−sk = d(x,S). Fact. Any proximinal set is closed. (The points in S −S do not have a closest point in S.) Fact. Any Chebyshev set is a proximinal set. Fact. Any compact set is a proximinal set (due to Weierstrass theorem).
