因为不能作成半群,故更不可能作成左(右)零半群。
On account to cannot be semigroups, so cannot be left (right) zero semigroups absolutely.
特别地,我们还讨论了序零半群,给出了这类半群与偏序半群上的左整除关系链的关系。
In the paper we introduce the concepts of L-trivial, nil ordered semigroups and give every ordered semigroup is L-trivial if and only if the left divisibility relation is an order.
在给出它的若干特征之后,指出这一类半群也是群的矩阵的幂零元-理想扩张,但反之未必成立。
Also, after some prelimenaries, We have Obtained that the semigroup is further nil-extension of the matrix of groups, but the converse is not all true.
