  2. 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 ...

  4. Contraposition - Wikipedia

    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. Antisymmetric relation - Wikipedia

    en.wikipedia.org/wiki/Antisymmetric_relation

    All definitions tacitly require the homogeneous relation be transitive: for all ,,, if and then . A term's definition may require additional properties that are not listed in this table. In mathematics , a binary relation R {\displaystyle R} on a set X {\displaystyle X} is antisymmetric if there is no pair of distinct elements of X ...

  6. Transitive closure - Wikipedia

    en.wikipedia.org/wiki/Transitive_closure

    A relation R on a set X is transitive if, for all x, y, z in X, whenever x R y and y R z then x R z. Examples of transitive relations include the equality relation on any set, the "less than or equal" relation on any linearly ordered set, and the relation "x was born before y" on the set of all people. Symbolically, this can be denoted as: if x ...

  7. 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 ...

    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

  9. Torrent file - Wikipedia

    en.wikipedia.org/wiki/Torrent_file

    The torrent system has been created to ease the load on central servers, as instead of having individual clients fetch files from the server, torrent can crowd-source the bandwidth needed for the file transfer and reduce the time needed to download large files. Many free/freeware programs and operating systems, such as the various Linux ...
