【摘要】 研究了正则双序集上的完全半单半群同余,给出了这类同余的等价刻画,用≤表示正则双序集上的自然偏序,证明了是任意正则双序集上的最小完全半单半群同余.更多还原

【Abstract】 The completely semisimple congruences on a regular biordered set are investigated,some equivalent characterization of completely semisimple congruences are obtained.Let≤ be the natural partial order on a regular semigroup.We prove that is the least completely semisimple semigroup congruence on a regular biordered set.更多还原
