  2. Antisymmetric relation - Wikipedia

    The definition of antisymmetry says nothing about whether actually holds or not for any . An antisymmetric relation R {\displaystyle R} on a set X {\displaystyle X} may be reflexive (that is, a R a {\displaystyle aRa} for all a ∈ X {\displaystyle a\in X} ), irreflexive (that is, a R a {\displaystyle aRa} for no a ∈ X {\displaystyle a\in X ...

    In linguistics, antisymmetry is a syntactic theory presented in Richard S. Kayne's 1994 monograph The Antisymmetry of Syntax. [1] It asserts that grammatical hierarchies in natural language follow a universal order, namely specifier-head-complement branching order. The theory builds on the foundation of the X-bar theory.

  5. Dichromatic symmetry - Wikipedia

    A more precise definition is "operations of antisymmetry transform objects possessing two possible values of a given property from one value to the other." [9] Dichromatic symmetry refers specifically to two-coloured symmetry; this can be extended to three or more colours in which case it is termed polychromatic symmetry. [10]

    I believe there is a cycle in the definitions: Equality is defined as binary relation which is reflexive, symmetric transitive and antisymmetric. The definition of antisymmetry refers to the notion of equality (a R b and b R a => a = b). I don't know how to fix this. cheers, chris The '=' above is identity, not equality. Identity is primitive ...
