If every element of the semigroup is a left zero then the semigroup is called a left zero semigroup; a right zero semigroup is defined analogously.〔M. Kilp, U. Knauer, A.V. Mikhalev, ''Monoids, Acts and Categories with Applications to Wreath Products and Graphs'', De Gruyter Expositions in Mathematics vol. 29, Walter de Gruyter, 2000, ISBN 3-11-015248-7, p. 19〕 According to Clifford and Preston, "In spite of their triviality, these semigroups arise naturally in a number of investigations."〔 ==Null semigroup== Let ''S'' be a semigroup with zero element 0. Then ''S'' is called a ''null semigroup'' if for all ''x'' and ''y'' in ''S'' we have ''xy'' = 0. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Null semigroup」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
