作者 胡志斌 邱书明 《江西科学》 2009年第1期64-66,共3页
一个半群叫C-wrpp半群,如果每一个L**-类包含至少一个幂等元且幂等元是中心。研究C-wrpp半群的平移壳,证明C-wrpp半群的平移壳仍是C-wrpp半群。
关键词 c—wrpp半群 平移壳

In particular, the concept of left △-product is extended and enriched. The aim of this paper is to give a construction of left C-wrpp semigroups by a left regular band and a strong semilattice of left-R cancellative monoids. Properties of left C-wrpp semigroups endowed with left △-products are particularly investigated. 展开更多
关键词 left c-wrpp semigroup left regular band left △-product.
