摘　　要：设In是有限集Xn={1,2,…,n}上的对称逆半群,M(A)是In的半个传递子半群.本文研究了M(A)的Green-关系和Green-关系,并证明了它是类A半群.Let In be the symmetric inverse semigroup of Xn={1,2,…,n},M(A)be the half-transitive subsemigroup of In.This paper we investigates the Green-relations and the Green-relations of M(A),and proves that M(A)is a type A semigroup.

关 键 词：半群 类A半群 GREEN-关系
