subsemigroups

基本解释

A subsemigroup which is also a group is called a subgroup .
也是群的子半群叫做子群。
If S is a semigroup, then the intersection of any collection of subsemigroups of S is also a subsemigroup of S.
如果 S 是半群，則任何 S 的子半群的搜集的交集也是 S 的子半群。
For any subset A of S there is a smallest subsemigroup T of S which contains A, and we say that A generates T.
對於 S 的任何子集 A，存在 S 的包含 A 的一個最小的子半群 T，我們稱 A 生成 T。
In the paper,we give the definitions of fuzzy Archimedean subsemigroups,them We discuss algebraic charateristics and algebraic properties of fuzzy Archimedean subsemigroups.
Fuzzy 子代數的研究已涉及到半群的領域.;[1]、[2]討論了半群的 Fuzzy 雙理想和 Fuzzy 半素理想;[3]討論了半群 Fuzzy 正則子半群;本文給出了 Fuzzy 阿基米德子半群的定義;竝討論了此類Fuzzy 代數系統的代數特征與代數性質;它們恰好是普通阿基米德半群性質的推廣
This paper presents an necessary and sufficient condition for subsemigroup to be cone ofL-group，and discusses the problem of extension on preorder groups.
得到了子半群是L-群的正錐的一個充要條件，竝討論了先序群的擴展問題。
