摘要 设Sing_n是[n]上的奇异变换半群.证明了半群Sing_n是由秩为n-1的非群平方幂等元生成的,且它的非群平方幂等元秩为(n(n-1))/2. Let Sing_n be the semigroup of all singular transformations of[n].In the paper we show that the semigroup Sing_n is generated by non-group quasi-idempotents of rank n-1,and its non-group quasi-idempotent rank is(n(n-1))/2.
