摘要
基于幂半群的同余关系,首次给出了粗糙幂半群的概念,得到了粗糙幂半群的一些性质,还讨论了粗糙幂半群的同态与同构.
On the basis of the congruence relation of power semigroup, the concept of rough power semigroup is firstly given. Some properties of rough power semigroup are obtained. Finally, homomorphism and isomorphism of rough power semigroup are discussed.
