  Order theory - Wikipedia, the free encyclopedia
Order theory is a branch of mathematics that studies various kinds of binary relations that capture the intuitive notion of a mathematical ordering.
These are graphs where the vertices are the elements of the poset and the ordering relation is indicated by both the edges and the relative positioning of the vertices.
For example, a function preserves directed suprema iff it is continuous with respect to the Scott topology (for this reason this order theoretic property is also called Scott-continuity).

 Limit-preserving function (order theory) - Wikipedia, the free encyclopedia
In many specialized areas of order theory, one restricts to classes of partially ordered sets that are complete with respect to certain limit constructions.
For example, in lattice theory, one is interested in orders where all finite non-empty sets have both a least upper bound and a greatest lower bound.
Functions that preserve directed suprema are called Scott-continuous or sometimes just continuous, if this does not cause confusions with the according concept of analysis and topology.

For example, in lattice theory, one is interestedin orders where all finite non-empty sets have both a least upper bound and a greatest lower bound.
For example, functions that preserve the empty supremum are those that preserve the least element.Furthermore, due to the motivation explained earlier, many limit-preserving functions appear as special homomorphisms for certainorder structures.
Functions that preserve directed suprema are called Scott-continuous or sometimes just continuous, if this does not cause confusions with theaccording concept of analysis and topology.

Order theory captures the intuition of orders arises from such examples in a general This is achieved by specifying properties that relation ≤ must have to be a order.
Order isomorphisms are functions that define such a An order-isomorphism is a monotone bijective function that has a monotone inverse.
For example a function preserves suprema iff it is continuous with respect to the Scott topology this reason this order theoretic property is called Scott-continuity).

In the mathematical area of order theory, one often speaks about function s that preserve certain limits, i.e.
The categorical concept of limit-preserving and limit-reflecting functor s is in complete harmony with order theory, since orders can be considered as small categories of a certain kind.

 Completeness (order theory) - InformationBlast
In the mathematical area of order theory, completeness properties assert the existence of certain infima or suprema of a given partially ordered set.
On the one hand, these special elements often embody certain concrete properties that are interesting for the given application (such as being the least common multiple of a set of numbers or the union of a collection of sets).
An order in which all finite sets have both a supremum and an infimum is called a lattice.

For a quick lookup of order theoretic terms, there is also an order theory glossary.
In addition, order theory does not restrict to the various classes of ordering relations, but does also considers appropriate functions between them.
It is reasonable to require that functions between partially ordered sets have certain additional properties, that are related to the ordering relations of the two sets.

However, they have the additional property of being total, i.e., for all distinct a and b in P, we have that: :''a'' ≤ b or b ≤ a (totality) These Orders can also be called linear orders or chains.
Formally, an element m is minimal if: : a ≤ m implies a = m, for all elements a of the order.
