对两个ω链的0-直并T的Munn半群TE的结构进行了分析,刻画了TE的元素形式、乘法公式、Green关系,并讨论了这类Munn半群由同余对生成的最小正规同余,根据所得的结论对其同余格作出了分析.
In this paper,the Munn semigroup TE for 0-union E of two co-chains is characterized;the form of its elements,the multiplication formula and the Green’s relations on TE are given. The least normal congruence generated by congruence pair is discussed from which the congruence lattice is analyzed.
