<< review queue entry 49396 - submitted by 'brianlawrence' >> http://zh.wikipedia.org/wiki/%E7%AD%89%E4%BB%B7%E5%85%B3%E7%B3%BB 设 R 是某個集合 A 上的一个二元关系。若 R 满足以下條件： 自反性：\forall x \in A,~~x R x 对称性：\forall x, y \in A,~~ x R y ~~ \implies ~~y R x 传递性：\forall x, y, z \in A, ~~~( x R y ~~ \wedge ~~ y R z) ~~\implies~~x R z 则称 R 是一個定义在 A 上的等价关系。 (Paraphrase: An equivalence relation is a relation satisfying the axioms of reflexivity, symmetry, and transitivity.) |
