格序半群的一些性质

Some properties of lattice-order semigroups

主要利用格序羊群的对偶同构这一工具，研究格序半群的一些性质，并给出格半群构成格序群的一个充分必要条件．

In this paper,the author studied the properties of lattice - order semigroups and gave a sufficient and necessary conditin for a lattice - semigroup as a lattice -order group by using the tool of a dual isomorphism.
