摘要 设Xn={1,2,…,n}(n≥4)是一个自然序集,Wn是Xn的保序压缩奇异变换半群,K*(n,r)={α∈Wn:|imα|≤r}(1≤r≤n-1)是Wn的理想,证明了当r=1时,rank(K*(n,r))=n;当r>1时,rank(K*(n,r))=Cn-1r-1。 Let Xn={1,2,…,n}(n≥4) be natural order set,and Wn be a semigroup of the order-preserving and compressing singular transformations,K*(n,r)={α∈Wn:|im α|≤r}(1≤r≤n-1) be ideals of Wn.It is shown that rank(K*(n,r))=n when r=1;and rank(K*(n,r))=Cr-1n-1 when r1.
