摘要 设[n]={1,2,…,n}是正自然数集,C_n和PC_n分别为[n]上的保序且降序变换半群和保序且降序部分变换半群.记SPC_n=PC_n\C_n.对n≥5,证明了半群SPC_n的秩为n^2-n+1. Let[n]= {1,2,…,n}be a natural order set,Cn and PCn be the semigroups consisting of order-preserving or order-decreasing transformations and partial order-preserving or order-decreasing transformations on [n],respectively.Denote SPCn=PCn/Cn,it is called the order-preserving and order-decreasing stricty partial transformations semigroups.For n≥5,it is given that the rank of the semigroup SPCn is n^2-n+1.
