  3. Transitive relation - Wikipedia

    en.wikipedia.org/wiki/Transitive_relation

    In mathematics, a binary relation R on a set X is transitive if, for all elements a, b, c in X, whenever R relates a to b and b to c, then R also relates a to c. Every partial order and every equivalence relation is transitive. For example, less than and equality among real numbers are both transitive: If a < b and b < c then a < c; and if x ...

  4. Contraposition - Wikipedia

    en.wikipedia.org/wiki/Contraposition

    The inverse is "If an object is not red, then it does not have color." An object which is blue is not red, and still has color. Therefore, in this case the inverse is false. The converse is "If an object has color, then it is red." Objects can have other colors, so the converse of our statement is false.

  5. Release print - Wikipedia

    en.wikipedia.org/wiki/Release_print

    In the traditional photochemical post-production workflow, release prints are usually copies, made using a high-speed continuous contact optical printer, [5] of an internegative (sometimes referred to as a 'dupe negative'), which in turn is a copy of an interpositive (these were sometimes referred to as 'lavender prints' in the past, due to the slightly colored base of the otherwise black-and ...

  6. Direct–inverse alignment - Wikipedia

    en.wikipedia.org/wiki/Direct–inverse_alignment

    The definition of a direct–inverse language is a matter under research in linguistic typology, but it is widely understood to involve different grammar for transitive predications according to the relative positions of their "subject" and their "object" on a person hierarchy, which, in turn, is some combination of saliency and animacy specific to a given language.

  7. Intransitivity - Wikipedia

    en.wikipedia.org/wiki/Intransitivity

    The first argument of the relation is a row and the second one is a column. Ones indicate the relation holds, zero indicates that it does not hold. Now, notice that the following statement is true for any pair of elements x and y drawn (with replacement) from the set {rock, scissors, paper}: If x defeats y, and y defeats z, then x does not ...

  8. Converse relation - Wikipedia

    en.wikipedia.org/wiki/Converse_relation

    In the monoid of binary endorelations on a set (with the binary operation on relations being the composition of relations), the converse relation does not satisfy the definition of an inverse from group theory, that is, if is an arbitrary relation on , then does not equal the identity relation on in general.

    Transitive set a set A such that whenever x ∈ A, and yx, then y ∈ A Topological transitivity property of a continuous map for which every open subset U' of the phase space intersects every other open subset V , when going along trajectory
