On the 0-union semilattice and munn semigroups;
关于0-并半格及其Munn半群
This paper introduces the new concepts of locally conditional upper semilattice (in short, L-cusl) and their ideal completions.
引入局部条件并半格 (简记为 L cusl)及其理想完备化等概念 。
The Semigroup Structure of Orthorings;
纯整环并半环的半群结构
To describe the congruences on orthorings,the concept of congruence-pair is introduced which is different from the method in regular semigroups.
不同于正则半群中的方法研究同余,为了刻画纯整环并半环上的同余,定义了纯整环并半环上的同余对。
