  2. Law of trichotomy - Wikipedia

    en.wikipedia.org/wiki/Law_of_trichotomy

    A law of trichotomy on some set X of numbers usually expresses that some tacitly given ordering relation on X is a trichotomous one. An example is the law "For arbitrary real numbers x and y, exactly one of x < y, y < x, or x = y applies"; some authors even fix y to be zero, [1] relying on the real number's additive linearly ordered group structure.

  3. Trichotomy theorem - Wikipedia

    en.wikipedia.org/wiki/Trichotomy_theorem

    In group theory, the trichotomy theorem divides the finite simple groups of characteristic 2 type and rank at least 3 into three classes. It was proved by Aschbacher (1981, 1983) for rank 3 and by Gorenstein & Lyons (1983) for rank at least 4.

  5. Trichotomy (philosophy) - Wikipedia

    en.wikipedia.org/wiki/Trichotomy_(philosophy)

    Important trichotomies discussed by Aquinas include the causal principles (agent, patient, act), the potencies for the intellect (imagination, cogitative power, and memory and reminiscence), and the acts of the intellect (concept, judgment, reasoning), with all of those rooted in Aristotle; also the transcendentals of being (unity, truth, goodness) and the requisites of the beautiful ...

  6. 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 .}

  7. Point-biserial correlation coefficient - Wikipedia

    en.wikipedia.org/wiki/Point-biserial_correlation...

    The point biserial correlation coefficient (r pb) is a correlation coefficient used when one variable (e.g. Y) is dichotomous; Y can either be "naturally" dichotomous, like whether a coin lands heads or tails, or an artificially dichotomized variable. In most situations it is not advisable to dichotomize variables artificially. [1]

  8. Epsilon-induction - Wikipedia

    en.wikipedia.org/wiki/Epsilon-induction

    The theory of Von Neumann ordinals describes such sets and, there, models the order relation <, which classically is provably trichotomous and total. Of interest there is the successor operation {} that maps ordinals to ordinals. In the classical case, the induction step for successor ordinals can be simplified so that a property must merely be ...

  9. Relation (mathematics) - Wikipedia

    en.wikipedia.org/wiki/Relation_(mathematics)

    If a relation is reflexive, irreflexive, symmetric, antisymmetric, asymmetric, transitive, total, trichotomous, a partial order, total order, strict weak order, total preorder (weak order), or an equivalence relation, then so too are its restrictions. However, the transitive closure of a restriction is a subset of the restriction of the ...
