**Ordered pair**— In mathematics, an ordered pair (a, b) is a pair of mathematical objects. In the ordered pair (a, b), the object a is called the first entry, and the object b the second entry of the pair. Alternatively, the objects are called the first and… … Wikipedia**ordered pair**— An object associated with a set of two objects considered in a particular order. Thus the ordered pair <a,b> is not identical with the ordered pair <b,a>, just as the queue ‘a first and b next’ is not the queue ‘b first and a next’.… … Philosophy dictionary**Ordered geometry**— is a form of geometry featuring the concept of intermediacy (or betweenness ) but, like projective geometry, omitting the basic notion of measurement. Ordered geometry is a fundamental geometry forming a common framework for affine, Euclidean,… … Wikipedia**Ordered logit**— In statistics, the ordered logit model (also ordered logistic regression or proportional odds model), is a regression model for ordinal dependent variables. It can be thought of as an extension of the logistic regression model for dichotomous… … Wikipedia**Ordered vector space**— A point x in R2 and the set of all y such that x≤y (in red). The order here is x≤y if and only if x1 ≤ y1 and x2 ≤ y2. In mathematics an ordered vector space or partially ordered vector space is a vector space equi … Wikipedia**Ordered graph**— An ordered graph is a graph with a total order over its nodes. In an ordered graph, the parents of a node are the nodes that are joined to it and precede it in the ordering. More precisely, n is a parent of m in the ordered graph if and n < m … Wikipedia**Partially ordered set**— The Hasse diagram of the set of all subsets of a three element set {x, y, z}, ordered by inclusion. In mathematics, especially order theory, a partially ordered set (or poset) formalizes and generalizes the intuitive concept of an ordering,… … Wikipedia**totally ordered set**— Math. a set in which a relation, as less than or equal to, holds for all pairs of elements of the set. Also called chain, linearly ordered set, simply ordered set. Cf. partially ordered set, well ordered set. * * * … Universalium**totally ordered set**— Math. a set in which a relation, as less than or equal to, holds for all pairs of elements of the set.
