  2. Total order - Wikipedia

    en.wikipedia.org/wiki/Total_order

    A strict total order on a set is a strict partial order on in which any two distinct elements are comparable. That is, a strict total order is a binary relation < {\displaystyle <} on some set X {\displaystyle X} , which satisfies the following for all a , b {\displaystyle a,b} and c {\displaystyle c} in X {\displaystyle X} :

  3. Weak ordering - Wikipedia

    en.wikipedia.org/wiki/Weak_ordering

    A strict weak order that is trichotomous is called a strict total order. [14] The total preorder which is the inverse of its complement is in this case a total order . For a strict weak order < {\displaystyle \,<\,} another associated reflexive relation is its reflexive closure , a (non-strict) partial order ≤ . {\displaystyle \,\leq .}

    In Lithuania the highest tuition is nearly 12,000 euros and 37 percent of the students pay. [4] Tuition fees in the United Kingdom were introduced in 1998, with a maximum permitted fee of £1,000. Since then, this maximum has been raised to £9,000 (more than €10,000) in most of the United Kingdom, however, only those who reach a certain ...

  6. Order theory - Wikipedia

    en.wikipedia.org/wiki/Order_theory

    Several types of orders can be defined from numerical data on the items of the order: a total order results from attaching distinct real numbers to each item and using the numerical comparisons to order the items; instead, if distinct items are allowed to have equal numerical scores, one obtains a strict weak ordering.

  7. Transitive relation - Wikipedia

    en.wikipedia.org/wiki/Transitive_relation

    Partial order – an antisymmetric preorder; Total preorder – a connected (formerly called total) preorder; Equivalence relation – a symmetric preorder; Strict weak ordering – a strict partial order in which incomparability is an equivalence relation; Total ordering – a connected (total), antisymmetric, and transitive relation

  8. Equivalence relation - Wikipedia

    en.wikipedia.org/wiki/Equivalence_relation

    The equivalence classes of an equivalence relation can substitute for one another, but not individuals within a class. A strict partial order is irreflexive, transitive, and asymmetric . A partial equivalence relation is transitive and symmetric.
