【摘要】 在深入研究完全rpp半群和C-wrpp的基础上,定义了完全wrpp半群,得到了完全wrpp半群的一些重要性质,即在完全wrpp半群中定义了一类关系η,证明了关系η是S上的同余,在此基础上,证明了Λ**-关系在商半群S/η中是遗传的。更多还原

【Abstract】 We introduce the concept of a perfect wrpp semigroup based on perfect rpp semigroups and C-wrpp semigroups,and we obtain some properties for perfect wrpp semigroups.Then we introduce the concept of a relationship η on a perfect wrpp semigroup S,and get a congruence η on the perfect wrpp semigroups.Based on it,Λ**-relationship is genetic on a operator semigroup S/η.更多还原
