【摘要】 对双单ω-半群的同余格与格林等价关系之间的关系进行了一些探讨,并得出了如下的结果:在两种类型的双单ω-半群上,关系P为C(S)上的同余;在另外两种类型的双单ω-半群上,关系P不一定是C(S)上的同余,给出了一些有用的结论.更多还原

【Abstract】 The paper studies the relation between congruence lattice and Green of relation on bisimple ω-semigroup.We prove that: the relation P is congruences on C(S) in two kinds of bisimple ω-semigroup;the relation P is not congruences on C(S) in other two kinds of bisimple ω-semigroup,and we give some important results.更多还原
