摘要: 设Xn={1,2,…,n}并赋予自然数序, MCn是Xn上的单调压缩奇异变换半群. 对任意3≤r≤n-1, 考虑半群MC(n,r)={α∈MCn: |Im α|≤r}, 得到了半群MC(n,r)的极大子半群的完全分类.

关键词: 单调压缩, 变换半群, 极大子半群

Abstract: Suppose Xn={1,2,…,n}, with the usual order of natural number sequence, MCn was the monotonic compression singular transformation semigroup on Xn. For any 3≤r≤n-1, we considered the semigroup MC(n,r)={α∈MCn: |Im α|≤r}, and obtained the complete classification of the maximal subsemigroups of the semigroup MC(n,r) on Xn.

Key words: maximal subsemigroup, transformation semigroup, monotonic compression
