毕竟PI-强wrpp半群

Eventually PI-Strong wrpp Semigroups

半群S的每个L(**)-类都含有幂等元,就称S为毕竟wrpp半群,特别地,如果对任意a∈S,La(**)∩Ia都只含唯一的幂等元a+,就称为毕竟强wrpp半群.该文的目的是研究满足置换恒等式的毕竟强wrpp半群,即所谓的毕竟PI-强wrpp半群,得到毕竟PI-强wrpp半群的结构刻画.

Each L（＊＊） class of a semigroup S contains at least one idempotent is called an eventually wrpp semigroup.In particular,if L（＊＊）a∩Ia contains one unique idempotent a＋ for all a∈S,then is called an eventually strong wrrp semigroup.The aim of this paper is to study eventually strong wrpp semigroup whose satisfy permutation idemtities,that is,eventually PI-strong wrpp semigroups,the structure of such semigroup is obtained.
