WebSuch T is visualised as a n-level tree. An n-tree is called pruned if all ρi are surjective. For a pruned n-tree, all its leaves are at the highest level n. The ﬁnite set of leaves of an n-tree T is denoted by T . The maps ρi are referred to as the structure maps of an n-tree. A morphism F : T →S, where S = [ℓn −1] −−−→ξn− ...

In mathematics, a surjective function is a function f such that every element y can be mapped from element x so that f(x) = y. In other words, every element of the function's codomain is the image of at least one element of its domain. It is not required that x be unique; the function f may map one or more elements of X to the same element of Y. The term surjective and the related terms injective and bijective were introduced by Nicolas Bourbaki, …
