左几乎半群中的理想

Ideals in Left Almost Semigroups

Qiaser Mushtaq, Madad Khan

摘要:

左几乎半群(LA-半群)或Abel-Grassmann广群(AG-广群)在几篇论文中得到了研究。本文讨论了LA-半群中的理想。特别地,我们证明了具有左单位元e的LA-半群S中的每个理想是素的当且仅当它是幂等元且S的理想集在包含下是全序的。我们证明了S的理想是素的当且仅当它是半素的且强不可约的。我们还证明了正则LA-半群S中的每个理想是素的当且仅当S的理想集在包含下是全序的。最后我们证明了S中的每个理想是素的当且仅当它是强不可约的,并且S的理想的集合形成一个半格。

英文摘要:

A left almost semigroup (LA-semigroup) or an Abel-Grassmann's groupoid (AG-groupoid) is investigated in several papers. In this paper we have discussed ideals in LA-semigroups. Specifically, we have shown that every ideal in an LA-semigroup S with left identity e is prime if and only if it is idempotent and the set of ideals of S is totally ordered under inclusion. We have shown that an ideal of S is prime if and only if it is semiprime and strongly irreducible. We have proved also that every ideal in a regular LA-semigroup S is prime if and only if the set of ideals of S is totally ordered under inclusion. We have proved in the end that every ideal in S is prime if and only if it is strongly irreducible and the set of ideals of S form a semilattice.
