摘要
本文利用(*,~)-好同余对刻画了正规纯正左消幺半群并半群上的(*,~)-好同余.此结果将正则半群中有关正规纯正群并半群上同余的相关结论推广到了r-wide半群中.
In this paper,(*,~)-good congruences on normal ortho-lc-monoids are characterized by means of(*,~)-good congruence pair.The result about congruences on normal orthogroups in regular semigroups is generalized to r-wide semigroups.
