WebIn discrete Maths, an asymmetric relation is just the opposite of symmetric relation. In a set A, if one element is less than the other, satisfies one relation, then the other element is not less than the first one. Hence, less than (<), greater than (>) and minus ( … WebSee first example below. In mathematics, especially in order theory, a preorder or quasiorder is a binary relation that is reflexive and transitive. Preorders are more general than equivalence relations and (non-strict) partial orders, both of which are special cases of a preorder: an antisymmetric (or skeletal) preorder is a partial order, and ...
