In mathematics, a handle decomposition of an m-manifold M is a union
where each is obtained from by the attaching of -handles. A handle decomposition is to a manifold what a CW-decomposition is to a topological space—in many regards the purpose of a handle decomposition is to have a language analogous to CW-complexes, but adapted to the world of smooth manifolds. Thus an i-handle is the smooth analogue of an i-cell. Handle decompositions of manifolds arise naturally via Morse theory. The modification of handle structures is closely linked to Cerf theory.

Famous quotes containing the word handle:
“Fat black bucks in a wine-barrel room,
Barrel-house kings, with feet unstable,
Sagged and reeled and pounded on the table,
Pounded on the table,
Beat an empty barrel with the handle of a broom,
Hard as they were able,”
—Vachel Lindsay (1879–1931)
