子半群 meaning in English
subsemigroup
Examples
- Two properties of infinite cyclic sub - semigroups
无限循环子半群的两个性质 - Some special subsemigroups of regular semigroups with an inverse transversal was discussed . these subsemigroups play a decisive role in constructing regular semigroups with an inverse transversal
摘要讨论了具有逆断面的正则半群的一些特殊子半群。这些子半群在构造具有逆断面的正则半群中起决定性作用。 - Furthermore , in the second chapter semidirect product of 5 and te is discussed . we have the result that it is also clifford quasi - regular semigroup . besides semidirect product of s and te is semilattice of quasi - groups
进一步，论文又在第h章中讨论了半群s和t的子半群te的半直积及其结构，得出了s和t ”的半直积也是clvj 。 - Finally , we show that is a semilattice of groups congru - ence if and only if ( na ) u is a seminormal subsemigroup on 5 , where pna is a group congruence on the semilattice congruence class sa of 5
在这一章的最后文章绪出了半群s上的半格同燃so上的群同余pno的并i ’ upe成为s上的群的半格同余的充分必要条件为u （ na切oeyoey是s的半正规子半群 - Next , in the paper the concepts of fuzzy rough subsemigroups and fuzzy rough ideals in a semigroup are first given . in the sense of intersecting sets , fuzzy rough sets of a fuzzy subsemigroup is proved to be its fuzzy subsemigroup , while that of fuzzy ideal is also proved to be its fuzzy ideal
进而，本文在半群中首次提出了模糊粗糙子半群和模糊粗糙理想的概念，在截集意义下，证明了模糊子半群的模糊粗糙集是模糊子半群，模糊左(右，双)理想的模糊粗糙集是模糊左(右，双)理想。
