摘要
研究加法半群是带,乘法半群是完全正则半群的半环上的格林关系,对D ·∩D +,D ·∩L +,D ·∩R +进行了刻画,给出了D ·∩D +是同余关系的充分必要条件.
It is studied the Green’s relation of semiring whose additive semigroup should be a band and multiplicative semigroup should be a completely regular semigroup. The characterization of relations D ·∩D +, D ·∩L +, D ·∩R + is carried out and the sufficient and necessary condition of D ·∩D + being congruence relation is given.
