摘要
得到了矩形带的O-并B的Hall半群S,得出了S的乘法公式,Green关系及其结构,进一步讨论了S的幂等元集E(S)的最小正规迹(?),得到结论(?)=D^(E(S)),最后得到S的最大幂等元分离同余μ=ε.
The Hull Semigroup S of 0-unions of rectangular bands B is gained in this paper The elements' form, multiplication formulas and Greens' relations of S are got. Furthermore minimum normal trace T of E(S) is discussed. It is also proved that T=DE(S) and μ =ε.
