右e-wlpp半群的平移壳结构定理

The Translational Hull of Right e-wlpp Semigroups

根据右e-wlpp半群,给出了适当右e-wlpp半群的定义;利用适当右e-wlpp半群和幂等元集E(S)之间的关系,引入了S到自身的映射λ^+和ρ^+,从而证明了wlpp半群的平移壳是wlpp半群、适当右e-wlpp半群的平移壳是适当右e-wlpp半群.

The definition of adequate right e-wlpp semigroup is given according to the right e-wlpp semigroup.The mappingλ^+andρ^+from S to itself is introduced using the relation between adequate right e-wlpp semigroup and idempotent set E(S).It is proved that the translation hull of right e-wlpp semigroup is still right e-wlpp semigroup.The translation hull of an adequate right e-wlpp semigroup is still an adequate right e-wlpp semigroup.
