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. A surface embedded in three-dimensional space is closed if and only if it is the … WebMar 24, 2024 · The embedded disk in this new manifold is called the -handle in the union of and the handle. Dyck's theorem states that handles and cross-handles are equivalent in the presence of a cross-cap .

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.
