摘要
讨论正则半群上与格林关系有关的同余生成的格,研究这个格的Hasse图的几种退化情形,然后确定逆半群和两类特殊的完全正则半群上与格林关系有关的同余所生成的同余格.
It is discussed the lattice of congruences on a regular semigroup generated by the congruences generated by Green＇ s relations. Some degenerate cases of the Hasse diagram of this lattice are studied, and then these lattices on inverse semigroups and two special classes of completely regular semigroups are determined.
