摘要
通过引入满足置换恒等式的强wrpp半群的定义,得到了满足置换恒等式的强wrpp半群的一些性质。通过引入正规带上的最小半格同余ε,证明了当E(S)是矩形带时,满足置换恒等式的强wrpp半群是交换R-左可消幺半群与矩形带的直积。
In this paper, we introduce strongly wrpp semigroups which satisfy permutation identities. Then we obtain some properties for such semigroups. By introducing the minisemilattice congruence ε on the normal band B, on the condition of E(S) being a rectangular band, it is shown that a strongly wrpp semigroup,which satisfies permutation identities, is the direct product of a commutative p - left cancellative monoids and a rectangular band.
