A closed surface is a surface that is compact and without boundary. Examples of closed surfaces include the sphere, the torus and the Klein bottle. Examples of non-closed surfaces include an open disk (which is a sphere with a puncture), a cylinder (which is a sphere with two punctures), and the Möbius strip.

WebTheorem 0.1. Every rotational equivalence class in X n has exactly n + 1 elements. Of these, exactly one is an augmented Dyck path. Therefore, there is a bijection between Dyck paths and rotational equivalence classes. Proof. First, every equivalence class has at most n+1 members, since each path in X contains n+1 up-steps.
