摘要 设Tn是Xn={1,2,…,n}上的全变换半群.设ρ是Xn上的一个等价关系,≤是Xn/ρ上的一个全序.对Xn上Tn的划分递减子幺半群T(ρ,≤)={α∈Tn:(xα)ρ≤xρ,x∈Xn},在此刻划出它的Green*关系以及当n≥3时它既不是逆半群也不是完全正则半群. Let Tnbe the full transformation semigroup on a finite set Xn= { 1,2,…,n}. Let ρ be an equivalence relation on Xn,and let≤ be a total order on the set Xn/ ρ. Then,the partition decreasing submonoid of Tnon Xnis:T( ρ,≤) = { α ∈ Tn:( xα) ρ ≤ xρ,x ∈ Xn}.The Green's* relations of T( ρ,≤) is described,and T( ρ,≤) is never an inverse semigroup or a completely regular semigroup if n≥3.
