  Extreme value - Wikipedia, the free encyclopedia
In the case of a general partial order one should not confuse a least element (smaller than all other) and a minimal element (nothing is smaller).
Likewise, a greatest element of a poset is an upper bound of the set which is contained within the set, whereas a maximal element m of a poset A is an element of A such that if m ≤ b (for any b in A) then m = b.
In a totally ordered set, or chain, all elements are mutually comparable, so such a set can have at most one minimal element and at most one maximal element.

A minimal element of the partially ordered set of ideals of a given type of some algebraic system.
In a semi-group with minimal left ideals every left ideal contains a minimal left ideal, and the union of all minimal left ideals (which are pairwise disjoint) is the kernel of the semi-group.
The presence of minimal ideals in a primitive ring makes it close to a matrix ring in the following sense: A primitive ring with a non-zero socle is isomorphic to a dense subring of the ring of all linear transformations of some vector space over a skew-field, containing all transformations of finite rank.

The first element of the pair is found by adding the minimal element to each of the partial pull-off sequences.
When all the elements have been removed from the poset, purplpst is the standard form and the first pull-off sequence in pairlst gives an inverse isomorphism from the poset to this form.
The second argument is an element of the poset that is a green bubble.

 Maximal element - Wikipedia, the free encyclopedia
In mathematics, especially in order theory, a maximal element of a subset S of some partially ordered set is an element of S that is not smaller than any other element in S.
This example also shows that maximal elements are usually not unique and that it is possible for an element to be both maximal and minimal at the same time.
Yet, in a totally ordered set, the terms maximal element and greatest element coincide, which is why both terms are used interchangeably in fields like analysis where only total orders are considered.

M in the form (a, x) - the minimal element(s) are the "ancestors" of all other elements; and of course there can be no (x, a) for any minimal a, since R must be antisymmetric.

 Order Relation   (Site not responding. Last check: 2007-10-14)
The elements in a finite poset can be ordered linearly in a number of ways while preserving the partial order.
It is based on the fact that a finite poset has at least one minimal element.
The basic idea of the topological sorting is to first remove a minimal element from the given poset, and then repeat that for the resulting set until no more elements are left.

It is the minimal unit in the sound system which is not a sound per se, but a distinctive element within that sound system.
Therefore, a phoneme is the abstract element of sound, identified as being distinctive in a particular language.
It took even longer than that before formal linguistics, as the study of the abstract linguistic forms and their internal relations (phonology, morphology and syntax), opened some space for functional linguistics, which is primarily concerned with the forms of language in reference to their social function in communication (semantics and sociolinguistics).
