[edit]Noun
[edit]total order (plural total orders)
- (set theory, order theory) A partial order, ≤, (a binary relation that is reflexive, antisymmetric, and transitive) on some set S, such that any two elements of S are comparable (for any x, y ∈ S, either x ≤ y or y ≤ x).

- […] we conclude §2.1 by showing how, given a triangulation (i.e., simplicial decomposition) of a closed oriented 3-manifilld , and a total order '' on the set of vertices of , as well as a choice of a system of orthonormal bases for various Hilbert spaces that get specified in the process, we may obtain a complex number .

- Example 6.2.2. Suppose A is a finite set and R is a partial order on A. Prove that R can be extended to a total order on A. In other words, prove that there is a total order T on A such that R ⊆ T.

- A binary relation R defines a total order on a set X just in case for all x, y, z ∈ X, the following four conditions obtain: (1) Rxx (reflexivity), (2) Rxy & Ryz → Rxz (transitivity), (3) Rxy & Ryx → x = y (weak antisymmetry), and (4) Rxy ∨ Ryx (comparability). Bearing in mind that the relata of the total order are not events in , but entire equivalence classes of simultaneous events, it is straightforward to ask ≤ to be a total order of .
