Lexicographical Order - Definition
... Given two partially ordered sets A and B, the lexicographical order on the Cartesian product A × B is defined as (a,b) ≤ (a′,b′) if and only if a < a ... If A and B are totally ordered, then the result is a total order as well ... one can define the lexicographic order on the Cartesian product of n ordered sets, on the Cartesian product of a countably infinite family of ordered sets, and on the union of such sets ...

Back-and-forth Method - Application To Densely Ordered Sets
... Suppose that (A, ≤A) and (B, ≤B) are linearly ordered sets They are both unbounded, in other words neither A nor B has either a maximum or a minimum They are densely ordered, i.e ... Fix enumerations (without repetition) of the underlying sets A = { a1, a2, a3, … }, B = { b1, b2, b3, … } ... In the easy case of unbounded dense totally ordered sets it is possible to avoid step 2 by choosing the element bj more carefully (by choosing j as small as possible), but this does not work for more complicated ...
Paradoxes Of Set Theory - Basics - Ordinal Numbers
... cardinality, which describes the size of a set, ordered sets also form a subject of set theory ... The axiom of choice guarantees that every set can be well-ordered, which means that a total order can be imposed on its elements such that every nonempty subset has a first element ... The order of a well-ordered set is described by an ordinal number ...
Colexicographical Order
... or colex order, is a natural order structure of the Cartesian product of two or more ordered sets ... Given two partially ordered sets A and B, the colexicographical order on the Cartesian product A × B is defined as (a,b) ≤ (a′,b′) if and only if b < b′ or (b = b′ and a ... If A and B are totally ordered, then the result is a total order also ...
