摘要: 设自然数n≥4, Xn={1,2,…,n}。利用非单点性定义全变换半群的一类新的子半群——1-奇异变换半群,记作Tn(1)。 通过幂等元分析法确定Xn上1-奇异变换半群Tn(1)的最小生成集之后,证明Tn(1)的秩为n。

Abstract: Let n≥4, and Xn={1,2,…,n}. A new class of subsemigroups, 1-singular transformation semigroups of total transformation semigroups, is defined by non-singleton property, denoted by Tn(1). After determining the minimum generating set of the 1-singular transformation semigroup Tn(1)on Xn by idempotent analysis, it is proved that the rank of Tn(1)is n.

Key words: 1-singular transformation, semigroup, rank
