具有逆断面的正则半群上与格林关系有关的同余

The Congruences on Regular Semigroups with Inverse Transversals Associated with Green's Relations

  • 摘要: 利用商半群中元素的提升性和同态像中格林关系的提升性, 研究由格林关系和格林关系在具有逆断面的正则半群S的重要子半群上的限制所生成的同余, 确定这些同余所对应的半群类.

     

    Abstract: Let S be a regular semigroup with an inverse transversal. Following the study of the lifting property of ele-ments in the quotient semigroup of S and the lifting property of Green's relations in the homomorphic image of S, congruences on S generated by Green's relations and by restriction of Green's relations to the important subsemi-groups of S are investigated. The classes of semigroups related to these congruences are described.
