摘要
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。
A semigroup is called a C-wrpp semigroup if (i) each L^**-class contains an idempotent and (ii) the idempotents are central. It is proved that the translational hull of a C-wrpp semigroup is still a C-wrpp semigroup.
