<< review queue entry 43980 - submitted by 'richwarm' >> A "one-to-one map" is an *injection*, not a bijection. A bijection is, by definition, both a) "one-to-one" (i.e. an injection), and b) "onto" (i.e. a surjection) 單射（one to one或injective） 滿射（onto or surgection [sic]） 雙射（bijective）既是單射又是滿射的函數稱為雙射 http://zh.wikipedia.org/wiki/%E5%8D%95%E5%B0%84%E3%80%81%E5%8F%8C%E5%B0%84%E4%B8%8E%E6%BB%A1%E5%B0%84 (Wikipedia article 單射、雙射與滿射) |
